What are the Basic Signal Operations?Signal DefinitionA signal is defined as a set of information expressed as a function of independent variables, used as input or output in a system.Amplitude ScalingAmplitude scaling is a basic operation that changes the strength of a signal. It is represented as Y(t) = αX(t), where α is the scaling factor.Here, α is the scaling factor, where:- α<1 → signal is attenuated. α>1 → signal is amplified.Addition and MultiplicationThis particular operation invo
