6.7 HIGH-SIDE VERSUS LOW-SIDE INJECTION The choice of high-side or low-
side injection of the local oscillator into a mixer is based on 1 . The effect on the
signal being converted, 2. The frequency required of the mixer, and 3.
In addition to improving sensitivity (due to its gain) and improving selectivity (due
to additional tuned circuits), the RF amplifier also prevents the local oscillator
signal from radiating through the receiver antenna. The mixer has two inputs: the
...

Mixer and Local Oscillator The output of the RF amplifier is given to the mixer
stage. The local oscillator output is also applied to the mixer. Let us assume that
local oscillator frequency is /n and signal frequency is fs. The signal frequency fs

It has been noted that the local oscillator is designed to operate at 455 kHz above
the RF signal selected. Why not below it? Because it is much easier for the local
oscillator to track the RF if its frequency is above the RF. Tracking refers to ...

7.2.2 Radio frequency Filter Very often, the radio frequency bandwidth is wide
enough to allow noise at radio frequencies above and below the local oscillator
frequency to be mixed down to intermediate frequency, thus increasing
interference ...

It may be noted that picture and sound signals would remain in the same relative
position, i.e. , with sound carreir frequency higher than picture carrier frequency if
local oscillator frequency is set below, instead of above the carriers. The local ...
