IPC: H04N5/93
Filed: 1987-03-16
Abstract: PURPOSE:To correct an output reduction at the high area frequency of a reproducing a signal without giving distortion to a passing signal with a simple constitution by connecting serially a first primary high pass filter, a second primary high pass filter and a primary phase-shifting circuit. CONSTITUTION:The first primary high pass filter, the second primary high pass filter and the primary phase-shifting circuit are serially connected. Consequently, the selecting the constant of a resistor and a capacitor suitably, the phase characteristics of a high pass filter and a phase-shifting circuit are canceled, the initial purpose that the reduction at the high area frequency of a passing signal is corrected is attained, and on the other hand, the phase is not changed.

Abstract: PURPOSE:To prevent abnormal heat dissipation and damage of a transistor (TR) by connecting a parallel circuit comprising a resistor and a capacitor between a base and an emitter of a TR in a switching circuit where a power TR and an FET are connected in Darlington. CONSTITUTION:A TR 5 and an FET 5' are turned on at the same time in a transient state, a through-current flows and the TR may be damaged, in the switching circuit where the TR 5 and the FET 5' are connected in Darlington connecting circuit is connected in series between power supplies for complementary drive and an output is obtained from a connecting point. In this case, a parallel circuit comprising a resistor R and a capacitor C are connected between the base and emitter of the TR 5 to increase the base-emitter capacitance.
