BA7NXV 这是我在智谱上刷题遇到的,问一个峰峰值为100V的正弦波的有效值电压是多少? V有效值=峰峰值/√2 那这样就计算得出的答案应该是:约70.7V才对,但是智谱却认为是:35.4V。 网上查到的也应该是70.7V才对。 能讨论下为什么是35.4V吗?
BD3RBV BD3RBV This means that the peak-to-peak value of the signal is only 50, and therefore the RMS (root mean square) value is naturally 35.4.
BA7NXV BG2EWI Thank you for your detailed response and for providing the relevant values for square wave and sawtooth wave. I must also commend the excellent quality of the waveform drawings.
