the

original

in

the

frequency

and

time

domains.

Two

signals

are

compared

by

listening

to

their

tones.

The

procedure

is

repeated

using

a

double

tone

created

by

the

summer

circuit

of

laboratory

1.

FM

signals

are

generated

and

analyzed

in

the

time

and

frequency

domains.

The

HP8656B

signal

generator

is

also

introduced

in

this

lab.

Laboratory

4

demonstrates

the

concepts

of

frequency-division

multiplexing

(FDM)

and

time-division

multiplexing

(TDM).

FDM

signals

are

generated

via

laboratory

equipment

and

the

composite

signals

analyzed

in

the

frequency

domain.

The

HP8590B

Spectrum

Analyzer

is

introduced

for

this

purpose.

TDM

signals

are

produced

by

the

construction

of

a

circuit

that

uses

a

CD4051B

CMOS

analog

multiplexor

as

a

commutation

device.

The

TDM

signal

is

a

composite

of

four

signals

as

viewed

on

the

oscilloscope.

Laboratory

5

completes

the

assignments

with

the

detection

of

FM

signals

using

a

phase

locked

loop

(PLL).

The

PLL

is

wired

using

a

NE565

PLL

integrated

circuit.

The

demonstration

includes

the

free

running,

capture

and

lock

states

and

concludes

with

FM

demodulation.

The

design

notes

for

each

laboratory

are

outlined

in

the

following

chapters.

A

composite

list

of

laboratory

equipment

required

for

each

station

is

provided

and

compared

to

inventory

on

hand.
