RE Harmonics

Hi, I should have responded to this before which was also in Robert Macy's response. The sinx/x frequency response which he talked about is the result from a finite impulse signal repeated in x period of time. The square wave is a special case were the pulse width is 1/2 of the period. In the li

Hi, Robert Macy is correct in that I had reversed the harmonic attenuation rate for the triangle and square waveforms. The reason for this message is to point out that the Fourier Series approach to waveform analysis and hence the harmonic content of signal waveforms is based on the period of a s

Hi group, The answer and formula for harmonics is N*Hz. Hence, for the example, the second harmonic is 400 Hz when N=2, third harmonic is 600 Hz is when N=3, and so forth. The amount of harmonic content in a waveform is weather it is an even or odd or somewhere in between function. A triangle

Hi, There are messages on this server about DVM not being acceptable for measuring leak currents. There is also comments about aliasing problem found in some DVMs. As a designer of digital voltmeters, the sampling rate of the analog to digital converter in DVMs was set to a multiple period of th
