P-point transform analyzer using M N-point serial transform devices in parallel, the output signals therefrom being combined in K J-point serial transform devices in parallel, where M, N, K, and J are integers other than one such that MxN=KxJ=P. Serial input signals are converted to M parallel sets of signals which are coupled to the N-point transform devices for processing in subgroups. The subgroups of output signals are combined into the proper order by switching the output signals from the N-point devices to the J-point devices after suitable delays and phase shifting.
