Question
A given voltage signal f(t) = 4 cos? (20nt + 23°) – 6 cos (30nt + 68°) across 42. 1- Plot the amplitude and phase spectrum (double sided) of f(t). 2- Determine and sketch the PSD of f (t). || 3- Calculate the average power, using time domain and PSD. 4- Find and plot the output signal if f (t) is applied as an input to an ideal LPF having unity gain and 257 rad/sec bandwidth. 5- What will be the output signal if the bandwidth of the LPF in point 4 increases to 35n rad/sec?
