We have already discussed the time-variant impulse response w(ts) and the delay spread function \(g(t,\tau )\), which characterize a linear time-variant system completely and hence are called system functions. Now we will see that the latter provides meaningful Fourier transforms for applications in electrical engineering, and thus system functions in the frequency domain.
