Frequency Demodulation
Frequency modulation causes a carrier frequency to
deviate from its rest value by an amount linearly
proportional to the voltage of a baseband sig
Modulation And De-modulation
Radio Frequency Transmission
Information signal are transported between a transmitter and a
receiver over some form of transmission medium.
The information signal typically a voice and a digital signal is

1.4 Power Measurements
The decibel (dB) is a logarithmic unit that can be
used to measure ratios of virtually anything. In
the electronic communications, the decibel

RF engineering is very important in our daily activities.
We need radio and television for entertainment and nowadays,
we cant live without the mobile phone.
Why RF is so important?

Laboratory Exercise 6
Adders, Subtractors, and Multipliers
The purpose of this exercise is to examine arithmetic circuits that add, subtract, and multiply numbers. Each
type of circuit will be implemented in two ways: rst by writing VHDL code that describ
Laboratory Exercise 2
Numbers and Displays
This is an exercise in designing combinational circuits that can perform binary-to-decimal number conversion
and binary-coded-decimal (BCD) addition.
Part I
We wish to display on the 7-segment displays HEX3 to HE
Laboratory Exercise 4
Counters
This is an exercise in using counters.
Part I
Consider the circuit in Figure 1. It is a 4-bit synchronous counter which uses four T-type ip-ops. The counter
increments its count on each positive edge of the clock if the Enab
Laboratory Exercise 5
Clocks and Timers
This is an exercise in implementing and using a real-time clock.
Part I
Implement a 3-digit BCD counter. Display the contents of the counter on the 7-segment displays, HEX20. Derive
a control signal, from the 50-MHz

Combinational Logic Units
Combinational logic units are a type of
logic circuit whose output is a pure
function of the present input only.
Finite State Machines, used in sequential
logic, have
Mealy state machine
In the theory of computation, a Mealy machine is a finite state transducer that
generates an output based on its current state and input. This means that the state
diagram will include both an input and output signal for each transitio
