Hi,
The following is a part of IF section of a television receiver...
As it is being visible that the output response of the IF section in superheterodyne receiver has a sharp slope which is necessary for correction of output response of video detector. It has been said that this sharp slope is necessary so that it could provide an attenuation to the lower frequencies near the picture carrier so that they should not gets an extra amplification.
So my query is that how by modifying the output response of the IF section ( sharp slope) prevents lower frequency to gets amplified at the output of the video detector...??
