The application of narrow band dither operating at the Nyquist frequency to provide improved signal-to-noise ratio performance over conventional dither will be discussed. The increased magnitude of narrow band dither required to be equivalent to wide band dither will also be discussed. Experimental data comparing the performance of conventional narrow band dither signals operating at the Nyquist frequency to wide band dither signals will be presented.
