What is the peak to average ratio (PAR) in dB of the signals below:
- CW (Sine)
- FM
- GMSK
- BPSK
- AM 50%
- AM 75%
- AM 100%
- DSB
- SSB
- CW (Sine)
- FM
- GMSK
- BPSK
- AM 50%
- AM 75%
- AM 100%
- DSB
- SSB
- CW (Sine){ Sine wave so Av = .637 X Vrms, Peak = 1.4 X Vrms, so peak to Av. = 1.4/.637}
- FM { " }
- GMSK
- BPSK
- AM 50% *
- AM 75% *
- AM 100% *
- DSB *
- SSB *
* depends on peak to av. of modulation
