Solution:
A signal x(t) = cos(2πf1t) + cos(2πf2t) is sampled at a rate of 8 kHz. If f1 = 600 Hz and f2 = 1200 Hz, what is the frequency of the aliased component?
Solution:
A signal x(t) = cos(2πf1t) + cos(2πf2t) is sampled at a rate of 6kHz. If f1 = 600 Hz and f2 = 1200 Hz, what is the frequency of the aliased component?
Solution:
Consider the following system with impulse response h(t) = e^(-t)u(t), where u(t) is the unit step function. If the input to the system is x(t) = 3u(t), find the output y(t) of the system?
