The sampling of a function f(t) = sin(2πf0t) starts from zero-crossing. The signal can be detected, if sampling time T is:
What is the power and energy of the unit step sequence u(n) respectively?
For a periodic signal v(t) = 30 sin100t + 10 cos300t + 6 sin(500t + π/4), the
fundamental frequency in rad/s is
If a signal f(t) has energy ‘E’ the energy of the signal f(2t) is equal to:
Consider the sequence: x[n] = [- 4 - j5, 1 + j2, 4], the conjugate anti-symmetric part of the sequence is:
The function x(t) is shown in the figure. Even and odd parts of a unit step function u(t) are respectively:
