Two-dimensional chirp z-transform
WebOct 26, 2013 · \$\begingroup\$ @Li-aungYip, I think you may be conflating the Fourier series and the Fourier transform.The Fourier series is for periodic functions; the Fourier transform can be thought of as the Fourier series in the limit as the period goes to infinity. So, the Fourier transform is for aperiodic signals. Also, since periodic signals are necessarily time … WebTheapplicationsofcomputingz-transformsofftheunitcircle arefewer, butone is presented inthispaper, namely the enhancement of spectral resonances in systems for whichonehas some foreknowledge
