The transformations you have seen in the past can also be used to move and resize graphs of functions. We will be examining the following changes to f (x): - f (x), f (-x), f (x) + k, f (x + k), kf (x), f (kx) reflections translations dilations. Reflections of Functions: -f (x) and f (-x)
The time and frequency domains are alternative ways of representing signals. The Fourier. transform is the mathematical relationship between these two representations. If a signal is. modified in one domain, it will also be changed in the other domain, although usually not in the. same way. For example, it was shown in the last chapter that convolving time domain signals.
