Question A-003-002-003

Peak-Envelope Power (PEP) for SSB transmission is:

Correct Answer

Peak-Envelope Voltage (PEV) multiplied by 0.707, squared and divided by the load resistance

Explanation

PEP = (V_rms_at_peak_envelope)^2 / R. The RMS voltage at the peak of the envelope is PEV / √2 (or PEV * 0.707). So, PEP = (PEV * 0.707)^2 / R.
