Waveform correction filters

摘要

A number of wave correction filters are disclosed which respond to power surges or spikes outside the intended frequency and/or voltage for a load device. The circuits respond to such undesired frequencies and voltage levels by sensing and separating them from the desired voltage and frequencies and connecting the energy from such undesired voltages and/or frequencies to resistors where it is dissipated as heat. In this way, the resulting energy is prevented from distorting the input voltage to the load device. It is also retained in the filter and prevented from traveling through a ground connection to pollute other related circuits.
