Hello!
Recently I became interested in next question: theoretically there is a way to get a spectrum of wideband signal (band dF) if you can not follow the terms of Nyquest theorem when digitizing this signal? In other words what if I want to get the spectrum with minimal distortion of the wideband signal (with the band ΔF), but when digitizing this signal there is no possible to provide the sampling frequency Fs = 2ΔF (simply no way to get the ADC with higher sampling frequency). Prompt please, whether positively resolve the this problem? Also I will be grateful if you tell me what kind of books I can read to answer this question.
