A form of device in a television set that begins the process of converting a broadcast or CATV television signal into a video signal that can be displayed. Envelope detectors are sensitive to some of the modifications to television signals that have been proposed for receiver-compatible ATV systems.
Industry:Entertainment
A) Process of altering the frequency response of a video amplifier to compensate for high-frequency losses in coaxial cable.
b) The selective amplification or attenuation of certain frequencies.
Industry:Entertainment
The pulses which occur before and after the broad pulses in the vertical interval. These pulses help the horizontal oscillator to maintain synchronization. See equalising Pulses.
Industry:Entertainment
Pulses of one-half the width of the horizontal sync pulses which are transmitted at twice the rate of the horizontal sync pulses during the blanking intervals immediately preceding and following the vertical sync pulses. The action of these pulses causes the vertical deflection to start at the same time in each interval, and also serves to keep the horizontal sweep circuits in step during the vertical blanking intervals immediately preceding and following the vertical sync pulse.
Industry:Entertainment
Noise created by the input stage of an amplifier which appears in the output of the amplifier increased in level by the gain of the amp.
Industry:Entertainment
A control which adjusts the coupling of the bias oscillator to the erase head in a manner which purifies the oscillator’s waveform.
Industry:Entertainment
The minimum initial amplitude of a decreasing alternating field (normally applied in the longitudinal direction) required to reduce the output of a given recorded signal by a specified amount.
Industry:Entertainment
The noise arising when reproducing a bulk-erased tape with the erase and record heads completely de-energized.
Industry:Entertainment
A process by which a signal recorded on a tape is removed and the tape made ready for rerecording.
