Each

signal

component,

as

well

as

the

composite

wave,

are

measured

for

frequency,

period

and

amplitude.

The

increase

in

signal

bandwidth

is

also

measured.

LABORATORY

5:

PHASE

LOCKED

LOOP

The

phase

locked

loop

experiment

completes

the

lab

sequence.

This

circuit

is

constructed

using

a

NE565

PLL

integrated

circuit

based

on

the

National

Semiconductor

NE/SE565

specifications.

An

external

resistor

is

determined

by

the

student

using

the

equations

provided

in

the

lab.

These

equations

also

determine

the

center,

capture

and

lock

frequencies.

These

frequencies

are

then

measured

and

compared

to

those

predicted.

A

sine

wave

is

then

applied

to

the

PLL

and

the

capture

and

lock

ranges

are

exercised

by

varying

the

frequency.

An

FM

signal

is

then

generated

and

applied

to

the

circuit.

Demodulated

output

is

monitored

and

compared

to

input

as

the

frequency

is

varied.
