Bit Error Rate Performance
The Bit Synchronizer performance relative to theoretical is indicated below when the applied signal has an S/N radio is within 1 dB of the specified synchronization threshold with a Gaussian white noise bandwidth up to three times the bit rate, and has no jitter or base line variations on the input signal.
