Only one sample remains after noise filtering

Web24 de jul. de 2024 · Well, the RMS of a pure complex tone is 1.0, while a real tone is 0.707. On a Db scale that is a drop of 1.5. In "power" it's 3 dB. In particular, the SNR is low at zero crossings for a real tone, with the peak being the max. A complex tone is at max throughout the cycle. So, it's another tradeoff consideration. 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) − ...
