Solution:

A signal x(t) = cos(2πf1t) + cos(2πf2t) is sampled at a rate of 4kHz. If f1 = 600 Hz and f2 = 1200 Hz, what is the frequency of the aliased component?

4800 Hz.

1800 Hz.

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) = 4u(t), find the output y(t) of the system?

y(t) = 5e^-t(u(t) + 1)

y(t) = 4e^-t(u(t) + 1)

y(t) = 3e^-t(u(t) + 1)

y(t) = 2e^-t(u(t) + 1)

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) = 5u(t), find the output y(t) of the system?

y(t) = 5e^-t(u(t) + 1).

y(t) = 2.5e^-t(u(t) + 1).

y(t) = 4e^-t(u(t) + 1).

y(t) = 2e^-t(u(t) + 1).
