WHAT'S PWM, HOW TO MEASURE IT Calculating RMS voltage of a PWM. Thus for calculating RMS of a varying PWM voltage in response to a sine wave may be acquired by multiplying 0.7 (constant) with the peak voltage. So for a 9V peak we get 9 x 0.7 = 6.3V, that's the RMS voltage or the average value of a 9V peak to peak PWM simulating a sine wave. HOW TO MAKE A POWERFUL RF SIGNAL JAMMER CIRCUIT Adjust the right side 22p trimmer such that the meter reads around a maximum of 3V on the meter. This might disturb the initial frequency of the system that you might have set for the jamming purpose. So go back to the left side 22p trimmer and fine tune it again to set the desired frequency back into place. Your peak resonance for the circuitBLOG
