A continuous-time signal is a time-limited triangle function in the interval -1 to 1 and with unity amplitude. It is discretized and
N samples are stored.
a) What is a suitable sampling rate
Fs to reduce the effects of aliasing (hint: use the main lobe in the Fourier Domain to determine the signal bandwidth)?
b) What is the minimum number of samples
N needed to have frequency resolution of 0.25 Hz?
