Suitable sampling rate for triangle wave

1. What is a suitable sampling rate?
2. What is the minimum sampling rate when applying Nyquist theorem?
3. What would be the suitable sampling rate of a 100hz sine wave instrumentation?

What is a suitable sampling rate?

The Audio Engineering Society recommends 48 kHz sampling rate for most applications but gives recognition to 44.1 kHz for Compact Disc (CD) and other consumer uses, 32 kHz for transmission-related applications, and 96 kHz for higher bandwidth or relaxed anti-aliasing filtering.

What is the minimum sampling rate when applying Nyquist theorem?

Nyquist theorem in audio signals

Therefore, according to the Nyquist theorem, the optimal sample rate for the human ear is 40 kHz. This is why standard music and audio recording sample rates are close to this value. Any values greater than 40 kHz would be undetectable to most people.

What would be the suitable sampling rate of a 100hz sine wave instrumentation?

So, for the 100-Hz sine wave, your ADC should acquire the signal at a sample rate of more than 200 samples/s.
