Abstract:

Dynamic performance of an AD converter cannot be assessed by conventional tests since they employ low frequency inputs. In this report, a digital computer procedure is developed to determine the presence and extent of errors due to time jitter, nonlinearity, gain, quantization and locked bits. The procedure is based on discrete power spectrum analysis of recorded outputs of the AD converter using weighted or non-weighted sine wave input. A computer program is developed to compute the estimated power spectrum starting from discrete records of a signal and is used to show that a sine wave must be weighted to insure a narrow bandwidth.
