Placed the enlarger output's signal before is not the pure heart telecommunication number, among them in addition to mixing up with not a few works interference, still had considerable direct current or the low frequency weight.This design adopted a filter of a RC to come to in addition to these direct currents and low frequency weight.The time constant of a filter of RC is very big, will cause the slowness that its dynamic state respond to.Suppose it inputs to come a bigger jump to change the heart electricity line would the long time can't return zero.In order to remove this phenomenon, adopt the line of to reply zero electric circuits to remove this phenomenon.
Lead amplifier output signal is not purely psychological electrical signal, which in addition to a mixture of many workers frequency interference, there are considerable DC or low frequency weight. This design used a RC-filter to filter out high and low frequency of these direct current weight. RC time constants very high-Unit, will lead to the slow response to its dynamics. Assuming that the importation of a larger jump to the baseline will be prolonged not changed our hearts call back zero. To eliminate this phenomenon, using the baseline of zero circuits to eliminate this phenomenon.
