Since a delaying part () delays transmission of a video signal, the timing at which a decoded video signal is input into a multiplex processing part () matches the timing at which an analysis result from an encoded information analyzing partis received by the multiplex processing part (). It is, therefore, possible to perform processing for showing the quality level of a video on the same screen, and thus a large capacity memory is unnecessary.

A high-speed discrete Fourier transform (DFT) apparatus utilizes a processor operating in parallel with data acquisition to calculate terms of a Fourier transform corresponding to the incoming data. Since the processor calculates the Fourier terms in real-time, overall transformation time is substantially reduced and is limited by only the data acquisition time. In another aspect, substantial reduction of the number of computations are achieved by transforming the plurality of terms in Fourier equations at the same time. In a further aspect, the high-speed DFT is advantageously applied to a network analyzer which obtains a transfer function of a device in a frequency domain and converts the transfer function to a time domain response to a simulated test signal.
