i have function determined by: x(t)=sin[2*pi*(n/60)*p*t + sin(2*pi*m*(n/60)*t)] In the cases: n=1450 r.p.m. (rotating speed) p=20 , p=40, p=100 (pulses per revolution of an encoder) m=1, m=2 (multiplicity order of rotating speed) how to determine frequency sampling????

Sample it however frequent you want. The spacing between different values of t can be anything. What do you want? Exactly the Nyquist frequency? Something greater or lesser? How are we supposed to know? What is your goal? What are you trying to show, illustrate, or determine?
