shift key modulation (FSK) • Binary-phase shift key modulation (BPSK) • Quadrature-phase shift key modulation (QPSK) • Quadrature amplitude modulation (QAM) List of common digital modulation techniques The most common digital modulation techniques are: 1. Phase-shift keying (PSK): a. Binary PSK (BPSK)‚ using M=2 symbols b. Quadrature PSK (QPSK)‚ using M=4 symbols c. Differential PSK (DPSK) 2. Frequency-shift keying (FSK): a. Audio frequency-shift

Abstract The aim of this project is to demonstrate three of the Digital Modulation schemes used these days in Communications‚ which are the FSK(Frequency Shift Keying)‚ the PSK(Phase Shift Keying)‚ and the QPSK(Quadrature Phase Shift Keying)‚ and to design the electronic circuits for these systems on a single PCB(Printed Circuit Board). This board is to be used for educational purposes in

Data transmission‚ digital transmission‚ or digital communications is the physical transfer of data (a digital bit stream) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires‚ optical fibres‚ wireless communication channels‚ and storage media. The data are represented as an electromagnetic signal‚ such as an electrical voltage‚ radiowave‚ microwave‚ or infrared signal. Data representation can be divided into two categories: Digital

The purpose is to help students to gain experience in hardware construction‚ coordinated teamwork and project management. The design uses 74HC4046‚ a PLL integrated circuit (IC) made from CMOS technology A PLL is a closed loop frequency system that locks the phase of an output signal to an input reference signal.

Mobile communication has seen an unprecedented increase in the number of users over the past years. Its success in part is due to the various technologies that have been developed. It is not unlike other stationary communication systems in many respects however it does differ in others‚ one obvious one being the environment the signal and
