Cos(t)* δ (3t-2π)=

If the given system is causal, find the value of 'k':

Y(t) = x(t) - x(t+2k) + 0.5x(2t) + x(t-6)

If the Laplace transform of a signal Y(t) is Y(s) = 1 / (s(s-1)), then the final value of Y(t) is

What is the z-transform of n⁴?

A system has the transfer function (1-s)/(1+s). What type of system is it?

An example of a discrete set of information/system is

x(t) = 1 for |t| < 1
0 otherwise

Find y(t) = dx(t)/dt if the Fourier transform of x(t) is X(jω) = 2sin(ω)/ω

Find the Fourier transform of x(t) = e^-3t * u(t-3).

Amplifiers, motors, filters etc. are examples for which type of system?

Determine whether the given system is linear and time-invariant:

y(t) = (t+5) * x(t)
