peak-to-peak, average, and rms. if all the instantaneous values are averaged over a half-cycle, the result is the average voltage. for a sinewave, vav = vpeak. with r in figure equal to k ohms, the dc output would be the average value. but we usually find the rms value to be more useful because it is a measure

possible at only one frequency. accurate voltage measurement becomes very challenging as the frequency increases to or mhz. instead, power is measured using a thermal converter whose impedance is matched to the trans-mission line. if needed, the voltage can be calculated from the power and impedance. instrument...
