DSP Assignment, Deconvolution: 1. Abstract Convolution is a formal mathematical operation relating the input signal, output signal to/from a system and the impulse response of the system. 2. Introduction Convolution is a formal mathematical operation relating the input signal, output signal to/from a system and the impulse response of the system. Convolution is the operation where a single specimen of a sound is multiplied by every specimen of another sound. It is dissimilar from the normal multiplication of two sounds where a single specimen of the first sound is multiplied by the identical single specimen of a second sound. Deconvolution is the process of filtering a signal to compensate for an undesired convolution. …show more content…
