What is Fourier Transform Solutions for Signals about?

1) The Fourier transform of a signal x(t) is calculated from its derivative. Modulating a tenor voice signal and applying a filter is proposed to overlap the frequency ranges of tenor and alto voices. 2) A filter is suggested to select frequencies between 140Hz and 220Hz from a modulated tenor voice. However, the overlapping frequencies from modulation will distort the output. 3) The response of an LTI system to e^-αtu(t) is δ(t). The response to e^-αtcos(βt)u(t) is then derived to be δ(t) - βe^-αtsin(
