What is the nyquist rate of the signal x(t)=3cos(50*pi*t)+10sin(300*pi

1.	What is the nyquist rate of the signal x(t)=3cos(50pit)+10sin(300pit)-cos(100pit)?(a) 50Hz(b) 100Hz(c) 200Hz(d) 300HzI got this question by my college professor while I was bunking the class.I'm obligated to ask this question of A2D and D2A Converters in portion DSP – Basic Signaling of Digital Signal Processing
Answer» RIGHT CHOICE is (d) 300Hz The best explanation: The FREQUENCIES present in the given signal are F1=25Hz, F2=150Hz, F3=50Hz Thus Fmax=150Hz and from the SAMPLING THEOREM, nyquist rate=2Fmax Therefore, Fs=2150=300Hz.
