A time domain reflectometer (TDR) of output impedance 50- sends a step
voltage down a 50-2 transmission line that is terminated in an unknown
resistive load and displays the voltage at the sending end of the line, Figure

The TDR in part (a) is now connected to a metre-long 50 Q transmission line
which is terminated in a load of 100 N. Calculate and sketch the voltage at the
source for timet = 0 to t = 15 ns, given that the velocity of propagation on the
line is 2 x 10 m/s.
(2) What A minimizes slop-overload for DM system where the input is a normalized
sinusoidal, given f, = 30kHz and fm = 3kHz?
Question 1
In this homework, you are supposed to design a WBFM generator using Armstrong method. The
required WBFM should be able to transmit an audio signal of bandwidth 50HZ to 4kHz. Design an
Armstrong indirect FM modulator to generate an FM signal with carrier 100 MHz and Af 200 kHz.
A narrowband FM generator with fe = 100 kHz and 4f = 10 Hz is available. Only frequency tripplers
are available as frequency multipliers. In addition, an oscillator with adjustable frequency from 22 to
26 MHz is also available for mixing, along with bandpass filters of any specification. Show your work
to get full credit (labelled block diagram, complete calculations for local oscillator frequency etc.).
