Q:

How

do

the

plotted

spectra

components

compare

to

the

calculated

results

in

part

If?

A:

Plots

are

attached.

The

frequencies

and

amplitudes

were

close

to

those

calculated

in

If.

They

may

be

slightly

off

because

the

amplitude

of

the

message

signal

and

the

sample

pulse

may

not

be

exactly

5

(hard

to

read

on

Rapids

screen).

Only

the

odd

frequencies

are

present.

Q:

Does

varying

the

frequency

change

the

spectra

output

as

expected?

A:

Yes,

as

the

frequency

changes

we

can

watch

the

spectra

components

move

accordingly.

Q:

What

is

the

cutoff

frequency

of

the

LPF?

A:

1.074

Hz
