ABSTRACT:
A discrete chirp generator produces discrete chirp signals which correspond o either of two exponential functions, namely the functions exp [j.pi.(m.sup.2 +.alpha.)/N] or exp (j.pi.[m(m+.beta.)+.alpha.]/N), where m=0, 1, 2, . . . , M. Typically, M and N might both have the value 256.
Similarly, a discrete chirp filter is described by its impulse response which has one of these same two functional forms.
These two new components (discrete chirp generator and discrete chirp filter) can be used to implement
