To compute one of the following, multiply the peak-envelope voltage by 0.707 to obtain the RMS value, square the result and divide by the load resistance. Which is the correct answer?

Peak-Envelope Power (PEP) is defined as the average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle at the crest of the modulation envelope. To calculate standard power across a known load, you use the formula P = (V_RMS)^2 / R. When you measure the Peak-Envelope Voltage, you must first convert it to its Root Mean Square (RMS) equivalent. For a sine wave, this is done by multiplying the peak voltage by 0.707 (or dividing by the square root of 2). Squaring this RMS result and dividing by the load resistance perfectly satisfies the power formula to yield PEP. Distractors like ERP (Effective Radiated Power) involve antenna gain, while PIV (Peak Inverse Voltage) relates to diode voltage ratings.
