Signals: Generation, Modulation, Parameters,y, and/or phase. We will also talk about random, noisy-like sequences of numbers. The most important signal parameters will be defined, like mean value, variance, energy, power, RMS value, signal-to-noise ratio (SNR), and signal(s) correlation function. We will continue doing experiments with signal

Signal Orthogonal Transforms,composition weights are found by orthogonal transformation of signal samples, i.e. by multiplying them by rectangular orthogonal matrix having complex-conjugated decomposition functions in its rows. There are many sets of decomposition functions. We learn about: discrete cosine transforms (DCTs), di

Fast Fourier Transform,hy of all FFT algorithms in which inputs samples are recursively divided into smaller and smaller groups, finally the DFT is calculated upon very small data vectors, e.g. consisting of 2 or 4 elements, and next, recursively longer DFT spectra are reconstructed using shorter ones, up to obtaining the
