Signal processing using multilayer perceptron

... Introduction Digital signal processing is concerned with the processing of a discrete-time signal, called the input signal, to develop another discrete-time signal, called the output signal, with more ... original signal using specific digital signal processing algorithms. It is also possible to investigate the properties of a discrete-time system by observing the output...
