How do you sample a sine wave?

Digitizing the sine wave

We can thus use the formula s_n = A � sin(2πfn/sr) where n is a positive integer to generate samples for a frequency of f cycles per second. To make the arithmetic easier, imagine sr = 10,000 and f = 100. n should then range over 0 to 100 for one complete cycle to be output.

How do you solve sampling frequency?

The sampling frequency or sampling rate, f_s, is the average number of samples obtained in one second, thus f_s = 1/T. Its units are samples per second or hertz e.g. 48 kHz is 48,000 samples per second.

How do you find the frequency of a sine function?

In a sinusoidal model of the form y = a⋅sin(b(x−c))+d , the period is found by taking 2⋅π|b| . Frequency is the reciprocal of period. Example: y = 2⋅sin(3x) would have a period of 2π3 , which is one-third the length of the "normal" period of 2π .
