Question 1 of 27070

What is the approximate ratio of peak envelope power to average power during normal voice modulation peak in a single-sideband phone signal?

🔍 Key Concepts

• Single-sideband (SSB) phone operation and how voice peaks affect power • Difference between average power and peak envelope power (PEP) in radio transmissions • Typical modulation levels for normal voice (not overdriven or compressed) in SSB systems

💭 Think About

• Think about how often your spoken voice actually reaches its absolute peak level compared to its average level over a sentence. • Consider whether normal speech keeps the transmitter at maximum output all the time, or only during brief peaks. • Ask yourself: in common radio practice, is PEP just slightly higher than average power, many times higher, or extremely higher?

✅ Before You Answer

• Verify which choice reflects a realistic and commonly cited PEP-to-average power ratio for normal SSB voice (not shouting or overmodulating). • Eliminate options that imply the transmitter would be running near full power most of the time, since normal voice has pauses and varying loudness. • Check standard radio-operator references or study material for the typical PEP/average ratio used in examples of SSB voice operation.
