PSD of noise and desired signal is required to design Derivative-based filter Butterworth filter Wiener filter Notch filter

The phase plot of MA filter with symmetric tap weights is linear exponential non-linear quadratic

Synchronized averaging is more suitable for suppressing following type of noise: Shot noise White noise Gaussian noise Zero mean noise

The signal which is sampled at 500Hz has a power line artifact at 60 Hz. Find the location of zeros in the transfer function of the notch filter to remove the artifact at 60 Hz. 0.512+j0.66 0.512−j0.66 0.7289+j0.6845 0.7289−j0.6845

The transfer function of 4 points MA IIR filter is H(z)=14[1−z−41−z−1] H(z)=14[1−z−41−z−4] H(z)=14[1−z−2−z−41−z−1] H(z)=14[1−z−81−z−1]

If the first and second order moments of the process do not change with time then the process is weak sense stationary quasi stationary strict sense stationary non stationary
