The inverters incorporate the very latest surge and transient filtering circuits to ensure the trains stringent protection and EMC regulations are met. The output is a true sine wave of 230Vac at 50Hz ...

The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVEs). According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs ...

The threat of load shedding looms over the collective head of South Africa and rumours, facts and some hysteria swirl around much like pure sine waves. If you didn’t understand the sine wave bit ...

If a constant sine-wave of 0 VU is applied, the meter will achieve 0 VU in 300 ms. Readings on the VU scale are approximate to the base 10 of the power ratio referenced to that level. For a pure ...
