In modern power systems, analysis often requires the efficiency measurement between two asynchronous, periodic waveforms. For example, a variable-frequency drive with mains input generates a secondary AC output with selectable frequency for controlling the speed of an AC motor. To establish system efficiency, both swiftly and accurately, the input and output waveforms need to be […]
Analogue to Digital Converters (ADC) convert real world signals into binary code. A common misconception with ADCs is that the bit count is a key indicator of accuracy in a digital measurement. This leads to the notion that a higher bit count is the result of a more accurate instrument. There are a number of […]
