Abstract : A simulator generates a simulated broad-band signal that may include up to and in excess of 150 harmonics for communication and signal processing applications. Clock signals are fed to a number of counters which cyclically address an EPROM storage that provides a digital waveform pre-programmed as to bandwidth and harmonic content. The digital pre-programmed waveform is fed to a digital to analog converter having a high bit resolution, in excess of 14 bits, so that a broad-band signal having 150 or more harmonics can be accurately generated. The EPROMs may be reprogrammed in accordance with a desired output signal to give a considerable flexibility with regard to bandwidth and harmonic content.
