Transcribed image text: Consider the following signals. WebMay 22, 2024 · The convolution integral expresses the output of an LTI system based on an input signal, x ( t), and the system's impulse response, h ( t). The convolution integral is expressed as. y ( t) = ∫ − ∞ ∞ x ( τ) h ( t − τ) d τ. Convolution is such an important tool that it is represented by the symbol *, and can be written as. y ( t) = x ...
