yes you can. two samples are enough. nyquist is not 'theory'. it is a principle. umashankar, Go on, I'm a practical type so persuade me. :-) Record an ultrasonic cricket at 20 KHx, a shrew, a bat and the upper harmonics of a bird call and persuade me which is which with only two samples. :-) The Nyquist Theory is about aliasing, not resolution.
