摘要： A first operational amplifier (OP AMP) is connected at the positive input terminal to a signal input terminal. The positive output terminal of the first OP AMP is connected to a ground through a first capacitor, and to the positive input terminal of a second OP AMP. The positive output terminal of the second OP AMP is connected to positive input terminal of the first OP AMP via a second capacitor, and to the input terminal of a buffer. The output terminal of the buffer is connected to the negative input terminal of the first OP AMP, and to the positive input terminal of the first OP AMP via the connected series of the first and second resistors. The connection point of these resistors is connected to the negative input terminal of the second OP AMP. The output terminal of the buffer is connected to a signal output terminal. When the resistances of these resistors are equal, the circuit has a phase equalizer characteristic.

摘要： A noise-bar period detection circuit detects a noise bar period in response to a low-frequency carrier wave FM signal contained in a signal reproduced by a video head when a video tape is reproduced in a special mode so as to output a noise-bar detection signal. A reproduced-signal processing circuit including a clamp circuit, an AGC circuit and the like maintains normal voltage immediately before the noise bar period in response to the noise-bar detection signal output from the noise-bar period detection circuit. Therefore, restoration to a normal state can be performed immediately after the noise bar period.

摘要： A first operational amplifier differentially operates a signal to be adjusted input by an input unit and an adjusted signal output by an output unit. A second operational amplifier differentially operates a first output from the first operational amplifier and the adjusted signal. A buffer supplies a second output from the second operational amplifier to the output unit as the adjusted signal. A first adder obtains a sum component of a first signal obtained by multiplying a first variable m with the signal to be adjusted and a second signal obtained by multiplying a second variable 1-n with the adjusted signal. A first capacitor superposes the sum component of the first and second signals on the first output to supply a superposed signal to the second operational amplifier. A second adder obtains the signal to be adjusted or a component obtained by multiplying the first variable m with the signal to be adjusted as a third signal. A second capacitor superposes the third signal on the second output to supply a superposed signal to the buffer. The first and second variables m and 1-n are selected as desirable values in an adjusting mode and are respectively set to be m=n=1 (where 0.ltoreq.n and m.ltoreq.1) in a non-adjusting mode.

A signal at the luminance output terminal includes a signal component characterized by an amplitude in a color band frequency range, and the combiner outputs the signal having a signal component amplitude as (1) a first amplitude when the original color amplitude is small, and (2) a second amplitude when the original color amplitude is large, the first amplitude being greater than the second amplitude.

摘要： An active filter comprises a differential-type voltage-controlled current source. A first resistor is connected between the first input terminal of the voltage-controlled current source and a first signal source. A second resistor is connected between the second input terminal of the voltage-controlled current source and the second signal source (or the output terminal of the voltage-controlled current source). The incremental transfer conductance gm of the filter becomes smaller by R.sub.2 /(R.sub.1 +R.sub.2) compared to that of an active filter which does not contain the first and the second resistors of the active filter of the invention, where R.sub.1 and R.sub.2 are resistance values of the first and the second resistors, respectively.
