GENERAL

DESCRIPTION

The

circuitry

used

in

this

car

radio

incorporates

16

transistors

18

diodes

and

3

IC

(integrated

circuit).

An

external

antenna

feeds

the

AM

broadcasting

signal

to

the

converter.

The

AM

signal

then

goes

through

2

IF

amplifiers

to

the

diode

detector

and

then

to

the

audio

stages.

|

An

external

antenna

feeds

the

incoming

FM

or

FM

STEREO

broadcasting

signal

to

the

FM

RE

amplifier.

The

FM

mixer,

4

IF

amplifiers,

2

diodes

discriminator

and

multiplex

(MPX)

circuitry.

The

audio

signal

passes

through

the

2

IC

and

push-pull

audio

output

stages

for

each

channel.

An

AM

AVC

voltage

is

fed

back

to

the

RF

amplifier

and

Ist

IF

amplifier

circuit.

An

AFC

voltage

is

fed

back

to

the

FM

oscillator

circuit.
