What are the frequencies in the following signal?
Given a signal f(t)=e^-at (a>0), what will its fourier transform look like?
What is the Nyquist frequency of the sampling rate of 80 Hz?
A 200Hz sinusoidal signal is sampled at a rate of 240 samples/second. Spectral analysis of the sampled signal will reveal a peak at the following frequency:
The signal V(t) = X * sin(20*t*2π) + Y * cos(180*t*2π) is sampled at 100 samples/sec. The power spectrum of the sampled signal displays the following:
