WebbThe waveforms frequency, ƒ is determined by the number of cycles per second. In the United Kingdom this fundamental frequency is set at 50Hz while in the United States it is 60Hz. Harmonics are voltages or currents that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency.

WebbThe waveform representation of the class C commutation technique is given below: Here Ig 1 and Ig 2 represent the gate triggering pulses applied to thyristors T 1 and T 2 respectively. V T1 and V T2 are the voltage drops across T 1 and T 2 respectively. The current flowing through T 1 and T 2 respectively are represented by I T1 and I T2. WebbThere are 10 common waveform variations to look for, including: 1. Not symmetrical, shape. Repetitive waveforms should be symmetrical. That is, if you were to print the traces and cut them in two like-sized pieces, the two sides should be identical. A point of difference could indicate a problem. If the two components of the waveform are not ... the secret to giving great feedback - video
