The input to a filter is a discrete- time, zero- mean, random process whose autocorrelation function is RXX [n] = | a | n, for some constant a such that |a| A filter has a transfer function given by (a) Is this filter, lowpass, highpass, or bandpass? (b) Find the noise equivalent bandwidth of this filter. A square pulse of width to = 1µs plus zero- mean white Gaussian noise is input to a filter with impulse response, h (t) = exp (–t / t1) u (t). (a) Find the value of the constant such t1 that the SNR at the output of the ...Suppose we are allowed to observe a random process Z (t) at two points in time, to and t1. Based on those observations we would like to estimate Z (t) at time t= t2 where t0 < t1 < t2. We can view this as a prediction ...If the input to a linear filter is a random telegraph process with c zero- crossings per second and amplitude A, determine the output PSD. The filter impulse response is h (t) = bexp(– at) u ( t).Post your question
