TV color IF amplifier and detector. This configuration will provide approximately 84 dB voltage gain. The nominal 3-volt peak-to-peak output can be varied between 0 and 7 volts with excellent linearity and freedom from spurious output products. Alignment is most easily accomplished with an AM generator set at a carrier frequency of 45.75 MHz, modulated with a video frequency sweep. The detector tank is first adjusted for maximum detected DC witlra CW input. Next the video sweep modulation is applied in order to align the input and interstage circuits (courtesy GTE Sylvania Incorporated).
