Hetrodynig is action to get IF (intermediate frequancy.
when RF and frequancy genreated by Local osscilator mixed
in mixer then mixer produce IF.And phenomena called beat
frequancy.

Answer / rama kant sharma

hetrodyning is an action to convert high frequency(RF) to
required low frequency(Intermediate frequecy).when RF and
frequancy generated by Local oscillator mixed
in mixer then mixer produce IF.while locally generated freq
must be equal to the addition of RF and required
intermediate frequency (RF+IF).

we r saying that low pass rc filter will allow low frequency components n attenuates the high frequency components..but at low frequency reactance offer by capacitor is high..it will act as open circuit..hence there will no output..but practically we getting output. how?
