How is sample rate determined?

Sample rates are usually measured per second, using kilohertz (kHz) or cycles per second. CDs are usually recorded at 44.1kHz - which means that every second, 44,100 samples were taken. If you can master sample rates, you can create more accurate recordings.

Why CD sampling rate is 44.1 kHz?

The exact sampling rate of 44.1 kHz was inherited from PCM adaptors which was the most affordable way to transfer data from the recording studio to the CD manufacturer at the time the CD specification was being developed.

How do you calculate ADC sample rate?

For 28069, ADC converion time is 13 ADCCLKs(45MHz), then sample rate = 1/(13/45M)=3.46M. For 280049, ADC conversion time is 21 SYSCLKs (100MHz), and S/H time is 8 SYSCLKs, then the sample rate = 1/[(21+8)/100M]=3.45M.

How do you calculate sampling rate to avoid aliasing?

According to the Shannon Sampling Theorem, use a sampling frequency at least twice the maximum frequency component in the sampled signal to avoid aliasing.

What is the sampling rate of 44.1 kHz?

The sample rate of 44.1 kHz technically allows for audio at frequencies up to 22.05 kHz to be recorded. By placing the Nyquist frequency outside of our hearing range, we can use more moderate filters to eliminate aliasing without much audible effect.
