The first stage, which is shown in Figure. 4.66, is a high-order decimation filter that allows decimation by factors up to 1024. The maximum input sample frequency is 30 MHz.
Web20 de jul. de 2024 · White noise and its phase after narrowband bandpass filtering. Suppose w(t) is a white noise with uniform spectral density N0 / 2. It is bandpass filtered to get a narrowband white noise n(t) for fc − BT / 2 ⩽ f ⩽ fc + BT / 2. We write this in polar form by splitting into inphase and quad-phase wrt 2πfct. n(t) = nIcos(2πfct) − ...
