Abstract
The deconvolution problem for a cycle convolution equation with the input (or the deconvolution kernel) spectrum containing zeros is discussed. It is shown that through factorization of the kernel the impulse can be obtained by combined use of the two conventional methods: the Z -transform division method and DFT (discrete Fourier transform) division method, if the length of the impulse response is ⩽N -K , where N is the cyclic period and K is the number of kernel-spectrum zeros. Only deconvolution with noiseless data is considered
