Sampling, Aliasing & Nyquist Theorem
Sampling is a core aspect of analog-digital conversion. One huge consideration behind sampling is the sampling rate - How often do we sample a signal so we can accurately recreate it?
This may seem trivial at first, but serious problems can arise if we use a bad sample rate, as this can lead to aliasing - The failure to reconstruct the original signal, causing it to appear as a completely different wave of a lower frequency.
To combat this problem, we have to make use of the Nyquist-Shannon Sampling Theorem, which tells us what sample rate to use to prevent aliasing from happening. Today, we take a look at all these points and see just how they link together, to allow us to have the common sample rates (eg. 44100 Hz) we see today!

Music Technology 101: Sampling Rate and Bit Depth Explained
In this short video I will explain two widely used terms in music technology: sampling rate and bit depth. We'll also take a look at analog to digital conversion along the way.
What is an analog to digital converter? (ADC)
This is a small electronic unit inside your sound card which is responsible for converting the analog voltage measured by your microphone or other inputs into a series of binary numbers your machine can store and "understand". All data in your computer is in binary format, made out of 1s and 0s.
What is Sampling Rate?
Sampling rate determines how many points of a signal you acquire per unit time. It is usually measured in hertz, also abbreviated Hz, where 1 Hz = 1 point per second. Some other units you'll run into are:
1 kilohertz = 1 kHz = 1000 Hz

The simple lesson with sample rate is that more is better. But did you know that the method of achieving that high sample rate can actually distort your signal and throw off your measurements?
We all know sample rate as one of the banner specifications of an oscilloscope. We’ve been taught that the higher the sample rate, the better the measurement will be. Don’t get me wrong, this still holds completely true. However, there is something to be warry of. Do you know exactly how your oscilloscope is achieving that high sample rate? That could make a huge difference in your measurements.
Sample rate is the rate at which the sampler collects samples. The sample rate is measured in samples per second.
This rate ultimately affects the signal you see on screen. In a well-designed oscilloscope, samples will occur at a consistent rate with no variation.
Too low of a sample rate makes your signal look distorted and lacks signal detail. Under sampling could easily cause you to think that your signal is clean, when in fact it has several issues.
With a high sample rate we see a nice smooth representation of our signal and can make accurate measurements on it. So, the key point here is the higher the sample rate, the higher the resolution of the trace. This will allow you to make more accurate measurements of your signal and catch any errors that may exist.
However, you have to be warry of the method being used to achieve that high sample rate. This method can make or break your measurements, quite literally.
The problem I’m referring to is called Interleave Distortion.
To achieve high sample rates some scope vendors use 2 or more ADCs. The synchronized ADCs must have the same vertical gain, offset, and frequency response. If these interleaving requirements aren’t satisfied, the phase delay clocks will not be aligned causing inconsistent spacing between samples. The misaligned clocks cause the samples to be collected at varying intervals.
Much like the distorted signal with too low of a sample rate that we saw earlier, any measurements you make on a signal like this will be completely inaccurate.
So, in this case, the higher sample rate actually produces a less accurate waveform.
However, there are many cases where interleaving is implemented correctly, like with the Keysight S-Series oscilloscopes we’re using today. Interleaving isn’t something to be afraid of, just something to be cautious of.
In summary, always be cautious when you are working with both low and high sample rates. This is a key specification to monitor when you’re making measurements. Remember that the sample rate can automatically change as you adjust the time base settings, so be sure you are using the appropriate settings for the measurements you need to make.
The key things to remember about sample rate in your testing are:
1. Sample rate refers to the rate at which the oscilloscope can collect data points, in Sa/s
2. Too low of a sample rate can cause distortion and skew your measurements
3. And lastly, Interleaved ADCs will present an impressive sample rate specification; however, if they are not properly synchronized this method can distort your signal.
The sample rate is more than just an internal working of your oscilloscope. It has a profound impact on the trace you see. Sample rate determines whether you see an accurate representation of your signal, or a distorted one.
As an engineer creating new digital designs in a world of increasingly fast data rates and high-precision devices, you don’t have any room for unnecessary development delays. Don’t let your oscilloscope’s internal errors affect your measurements.

In this short video I will explain two widely used terms in music technology: sampling rate and bit depth. We'll also take a look at analog to digital conversion along the way.
What is an analog to digital converter? (ADC)
This is a small electronic unit inside your sound card which is responsible for converting the analog voltage measured by your microphone or other inputs into a series of binary numbers your machine can store and "understand". All data in your computer is in binary format, made out of 1s and 0s.
What is Sampling Rate?
Sampling rate determines how many points of a signal you acquire per unit time. It is usually measured in hertz, also abbreviated Hz, where 1 Hz = 1 point per second. Some other units you'll run into are:
1 kilohertz = 1 kHz = 1000 Hz
1 megahertz = 1 MHz = 1,000,000 Hz
1 gigahertz = 1 GHz = 1,000,000,000 Hz
1 terrahertz = 1 THz = 1,000,000,000,000 Hz
Of course, in audio only Hz and kHz are used, since those are the frequencies the human ear can hear. Higher frequencies are not encountered, although other non-audio digital electronics do use them.
For example, a sampling rate of 100 Hz means your ADC takes 100 points per second. Most audio cards operate at much higher sampling rates: 48 kHz, 96 kHz or even 192 kHz. This is related to a mathematical theorem called Nyquist's Theorem: the sampling rate of an ideal ADC should be at least twice the maximum frequency of your signal. Since our ears cannot hear above around 20-22 kHz - if they're really good! - sampling rates usually have to be at least around 40-44 kHz. Note that I said *ideal* ADC. Because of real-world non-ideal conditions, sampling rates are usually taken to be higher than twice the maximal frequency. This allows ADCs to deal better with their non-idealness.
Here's a pretty cool online hearing test, albeit not a very scientifically rigorous one, to help you determine the maximal frequency you can hear:
http://www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/
Sampling rate on Wikipedia:
http://en.wikipedia.org/wiki/Sampling_rate
What is Bit Depth?
Sampling rate tells you HOW MANY points you acquire per second. Bit depth tells you HOW DETAILED is each point. In computer jargon, this means how many bits of information you use to represent each point using binary numbers. Think of bit depth as putting a vertical ruler on your sound wave and rounding up each value to the nearest point on the ruler. The higher the bit-depth, the finer (smaller) the distance between the points. You can read about bit depth in more depth (pun intended) on Wikipedia:
