The signal degradation of a BPSK (binary phase-shift keying) signal with NRZ (nonreturn to zero) and biphase baseband signaling formats in the presence of CW (continuous-wave) spur is analyzed. CW spur is usually due to unintentional interference, and the degradation is usually small. The degradation is a function of the frequency and phase differences, the signaling format, and the nominal value of the BER (bit error rate). A BER analysis is performed, and typical numerical results are provided. It is shown that the signal degradation depends on the phase difference between the signal and the CW interference. The NRZ signal is more sensitive to the interference than the biphase signal.<>
