Communications Circuit Project

This is a communications circuits project that will require circuits to be designed and constructed. Since the project must be completed in one semester, all circuits will be implemented with discrete components rather than with integrated circuits.

The basic goal is to construct a transmitter, a receiver, and an interface to communicate between a computer and a robot with a maximum distance of 100 feet. The system must comply with Federal Communications Commission (FCC) standards. The system will transmit on a carrier frequency of approximately 27 MHz using differential phase-shift keying (DPSK) or on-off keying (OOK). The transmitted signals must be received and converted to the control signals required by the robot.

Four groups will be organized to work either on the computer/transmitter interface, the transmitter, the receiver, or the robot interface.

Some milestones that will be scheduled when the project begins are:

• Paper design of computer/transmitter interface.
• Implementation of computer/transmitter interface.
• Paper design of transmitter.
• Implementation of transmitter.
• Design of carrier oscillator.
• Design of modulator.
• Paper design of receiver.
• Implementation of receiver.
• Design of register/interface to robot.
