Assignment 2
Spring 2009
Problem 1
Plot two periods of square wave that is symmetric with respect to the
horizontal axis with peak value of 1 volt and a period of 1 sec.
On the same axis, plot
a)
the fundamental
b)
the first 7 harmonics
c)
the sum of the fundamental and the first 7 harmonics
Problem 2
What is
the THD of the Sherwood RX 4503 receiver?
Over what
frequency range is the amplifier in this receiver
specified to operate?
How much gain
deviation could occur over this frequency range?
Problem 3
Consider the circuit shown below.
a)
Determine the phasordomain transfer function relating V
OUT
and V
IN
b)
Obtain the corresponding sdomain transfer function
c)
Determine the steadystate output if V
IN
=0.5sin1000t
Problem 4
A power amplifier has an output impedance of 8
Ώ
and an opencircuit
RMS voltage of 64V
a)
Determine the power this amplifier will deliver to a 4
Ώ
load, to an 8
Ώ
load,
and to a 1K
Ώ
load
b)
What would be the opencircuit voltage of the amplifier if the signal level
