The result of the convolution x(−t) * δ(t − t0) is

The waveform of a periodic signal x(t) is shown in the figure. A signal g(t) is defined by g(t) = x((t − 1)/2). The average power of g(t) is

The pole-zero diagram of a causal and stable discrete-time system is shown in the figure. The zero at the origin has multiplicity 4. The impulse response of the...
