An ADC smaples at fs 1000Ss a What is the Nyquist frequency

An ADC smaples at f_s = 1000S/s.

(a) What is the Nyquist frequency of f_c of the ADC expressed in Hz?

(b) If the ADC measures a time-domain signal at frequencies f_sig = 655 Hz and f_sig = 1055 Hz at what frequencies do these signals apeear in the FFT?

Solution

a ) the nyquist frequency if 1000 / 2 = 500 hertz

b ) the nyquist frequency will apper .
