🔍 Key Concepts

• Relationship between PEP (Peak Envelope Power) and average power in SSB voice transmissions • How voice/speech waveform affects peak levels vs average levels • What factors (frequency, carrier suppression, amplifier rating) do and do NOT change the ratio between peak and average in normal SSB speech

💭 Think About

• Which choice relates directly to how often and how high the peaks occur compared to the average level in a voice signal? • Does changing the frequency of the audio, or the power capability of the amplifier, by itself alter how spiky the speech waveform is? • Which factor would change from one speaker to another, or one way of talking to another (e.g., soft vs. hard consonants), even if the radio equipment is the same?

✅ Before You Answer

• Identify which option is tied to the waveform shape of the audio modulation, not just hardware limits • Eliminate any choices that mainly affect maximum possible power rather than the ratio of peak to average • Ask: which factor would cause the PEP-to-average ratio to vary from moment to moment as you talk into the microphone?
