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)
Different from the discrete-time Fourier transform which converts a 1-D signal in time domain to a 1-D complex spectrum in frequency domain, the Z transform converts the 1D signal to a complex function defined over a 2-D complex plane, called z-plane, represented in polar form by radius and angle .
