Hello, I would appreciate if you can help me with personally prepared mathematical questions that are not available on the internet, which are not available on the following topics. Thanks... one) Power Limited Modlations. MFSK (Orthogonal-non-coherently detected). 2) Review of signals and systems, Fourier series expansion of periodic signals, Fourier transform, properties of Fourier transform, Convolution, correlation. 3) Sampling, Quantization, Pulse Code Modulation (PCM). 4) Optimal reception filter of binary polar transmission. Generalized binary signaling.
