A discrete signal is said to be even or symmetric if x(-n) is equal to

f(t) = r(t+1) - r(t)

For t > 0, what is the form of f(t)?

If the Laplace transform of f(t) is F(s), what is the value of the Laplace transform of e^-atf(t)?

Find the convolution sum of sequences x1[n] = (1, 2, 1) and x2[n] = (2, 1, 3)

If the gain margin of a certain feedback system is 20 dB, the Nyquist plot will cross the negative real axis at the point

If an amplitude-modulated DSB-FC (Double Sideband - Full Carrier) wave, with 100% modulation, has a total transmitted power of 10kW, what would be the power of the Upper sidebands?

If the total transmitted power, Pt, of an amplitude modulated DSB-FC (Double Side Band- Full Carrier) wave, for 100% modulation, is 100kW, what will be the approximate power used by the carrier wave?

The continuous time system described by the equation y(t) = x(t²) comes under which category?

consider a continuous-time system with input x(t) and output y(t) related by

y(t) = x(sin(t))

choose the correct option for the following system:

When we take up design of systems, ideally how do we define the stability of a system?
