and Average Calculator
|Waveform Type||Formula for RMS||Formula for Avg|
|Sine wave||Vrms= Vpk/sqrt(2)||Vavg= 0|
|Full rectified wave||Vrms= Vpk/sqrt(2)||Vavg= 0.637Vpk|
|Half rectified wave||Vrms= Vpk/2||Vavg= 0.318Vpk|
|Sine wave with DC offset||Vrms= *sqrt(Vdc2+Vpk2/2)||Vavg= Vdc|
|Half sine with duration T and frequency f||Vrms= Vpk*sqrt(f*T/2)||Vavg= 2f*T*Vpk/PI|
|Positive square wave with duration T and frequency f||Vrms= Vpk*sqrt(f*T)||Vavg= f*T*Vpk|
|Saw tooth wave with duration T and frequency f||Vrms= Vpk*sqrt(f*T/3)||Vavg= f*T*Vpk/2|
|Trapezoidal wave with frequency f, top segment T, and base segment B.||Vrms= Vpk*sqrt(f*((B-T)+3*T)/3)||Vavg= f*Vpk*((T+B)/2)|
This calculator will compute the RMS and average for some of the most common periodic waveforms.
