PRINCIPLE

OF

NOISE

REDUCTION

Much

of

the

audible

noise

is

a

hiss

noise

in

the

medium

and

high

frequencies

created

during

the

recording

process

on

magnetic

tape,

while

some

of

the

noise

is

playback

amplifier

noise.

At

high

input

levels

the

noise

is

suppressed,

however,

at

low

input

signal

levels

the

Signal

to

Noise

Ratio

(S/N)

decreases

and

the

noise

is

heard.

The

Dolby

System

in

this

unit

is

designed

to

solve

this

problem

by

boosting

the

low

level

mid

and

high

fre-

quencies

by

about

10

dB

during

recording

(com-

pressing)

and

attenuating

(expanding)

the

same

signals

during

playback

by

an

equal

amount,

as

shown

in

Fig.

4.

The

amount

of

boost/attenuation

depends

on

the

level

and

the

frequency

of

the

signal.

By

this

in

as

follows:

[ENCODE]:

ST3,

ST7,

ST11

and

ST9

in

RECORD

position.

The

recording

signal

is

applied

to

the

REC

AMP

and

passes

through

AMP

“A”

of

the

Dolby

IC

and

the

low-

pass-filter

(LPF),

and

enters

AMP

“B”

the

LPF

attenuates

unwanted

as

tape

recorder

bias

of

FM

MPX

sub.

carrier

signals

to

the

level

which

will

not

influence

the

Dolby

operation.

The

out-

put

signal

of

AMP

“B”

is

divided

into

two

paths;

one

is

directly

supplied

to

ADDER

“E”,

and

is

called

a

direct

signal,

while

the

other

controls

the

noise

signal.

This

signal,

passing

through

ST9,

S801-3,

high-

resistance

‘“F”

and

AMP

“C”,

enters

ADDER

“E”

and

increases

the

As

One

TUNING

SYSTEM

GENERAL

DESCRIPTION

The

FM

“Sensor

Touch”

Preset

Tuning

System

of

the

equipment

is

designed

for

an

easy

soft

touch

selection

of

six

stations.

This

system

is

composed

of

an

electronic

tuning

circuit

equipped

with

varactor

diodes

and

sensing

driver

cir-

cuit

using

two

integrated

circuits,

|C101

SN94041

and

IC102

SN94042.

CIRCUIT

OPERATION

The

operation

of

FM

“Sensor

Touch”

Preset

Tuning

System.

iC101

SN94041

operates

to

select

the

station

for

MANUAL,

P1

and

P2,

and

1C102

SN94042

is

for

P4,

When

the

sensor

button

of

P1

is

touched

with

a

finger,

the

detecting

circuit

of

P1

operates

to

energize

LED

driver

and

channel

out

circuit

and

then

a

LED

lights.

While

applying

voltage

that

is

adjusted

by

VR101

to

the

varactor

diode

of

the

electronic

tuning

circuit,

the

station

is

selected.

Muting

circuit

enables

to

decrease

selection

noise

when

selecting

channels,

by

flowing

the

signal

from

No.

6

of

IC

101

to

Q101.

Hold

circuit

and

reset

circuit

are

provided

to

lock

the

selected

station

when

releasing

the

finger.

Initial

Set

circuit

of

C101

operates
