12.5 AC Bridge Circuits
As we saw with DC measurement circuits, the circuit configuration known as a bridge can be a very useful way to...
12.4 Power Quality Measurement
It used to be with large AC power systems that “power quality” was an unheard-of concept, aside from power...
12.3 Power Measurement
Power measurement in AC circuits can be quite a bit more complex than with DC circuits for the simple reason that phase...
12.2 Frequency and Phase Measurement
An important electrical quantity with no equivalent in DC circuits is frequency. Frequency measurement is very...
12.1 AC Voltmeters and Ammeters
AC electromechanical meter movements come in two basic arrangements: those based on DC movement designs, and those...
7.5 Circuit Effects
The principle of non-sinusoidal, repeating waveforms being equivalent to a series of sine waves at different...
7.4 More on Spectrum Analysis
Computerized Fourier analysis, particularly in the form of the FFT algorithm, is a powerful tool for furthering our...
7.3 Other Waveshapes
As strange as it may seem, any repeating, non-sinusoidal waveform is actually equivalent to a series of sinusoidal...
7.2 Square Wave Signals
It has been found that any repeating, non-sinusoidal waveform can be equated to a combination of DC voltage, sine...
7.1 Introduction to Mixed-Frequency AC Signals
In our study of AC circuits thus far, we’ve explored circuits powered by a single-frequency sine voltage waveform. In...
