heal.abstract	Performance degradation of an analog PAL-G signal due to Direct Sequence Spread Spectrum overlay is examined. An analytical expression between RF TV protection ratio (CIR) and baseband unweighted Signal-to-Noise ratio (SNRv), for co-channel spread spectrum and noise interference, is derived. Computer analysis results are presented and compared to experimental measurements for different Spread Spectrum RF bandwidths and carrier frequency offsets between the analog and digital signal. Image quality degradation is also presented and associated to different level of Spread Spectrum interference.	en
