RMS Voltage of a Sinusoidal AC Waveform
VRMS = Vpk * 0.7071 = 20 x 0.7071 = 14.14V. Note that this value of 14.14 volts is the same value as for the previous graphical method. Then we can use either the graphical method of mid-ordinates, or the analytical method of calculation to find the RMS voltage or current values of a sinusoidal waveform.
What is Signal to Noise Ratio and How to calculate it ...
1/29/2020 · Furthermore, for power, SNR = 20 log (S ÷ N) and for voltage, SNR = 10 log (S ÷ N). Also, the resulting calculation is the SNR in decibels. For example, your measured noise value (N) is 2 microvolts, and your signal (S) is 300 millivolts. The SNR is 10 log (.3 ÷ .000002) or approximately 62 dB.
