Sinc interpolation of pure sine wave sampled just at Nyquist frequency

1. What will happen if we sample below the Nyquist rate?
2. What is the Nyquist sampling frequency for a signal with frequency?
3. What is the sampling frequency more than Nyquist rate called?
4. What is the Nyquist sampling rate formula?

What will happen if we sample below the Nyquist rate?

When the sampling frequency drops below the Nyquist rate, the frequencies will crossover and cause aliasing.

What is the Nyquist sampling frequency for a signal with frequency?

Nyquist's theorem states that a periodic signal must be sampled at more than twice the highest frequency component of the signal. In practice, because of the finite time available, a sample rate somewhat higher than this is necessary. A sample rate of 4 per cycle at oscilloscope bandwidth would be typical.

What is the sampling frequency more than Nyquist rate called?

When sampling frequency is greater than the Nyquist rate it is called as oversampling.

What is the Nyquist sampling rate formula?

Find Nyquist rate. 2n+2. n n = cos 2n+2.
