Our basic communications training lab is an integrated teaching solution aims to provide students with basic knowledge and technical concepts of telecommunication technology.
The Training units in this lab are specifically designed for hands-on training in a wide range of communication technologies. Training starts from the basic pulse modulation techniques (PAM, PWM, PPM, PCM, DPCM, and delta modulation), covers the various digital modulation schemes used in data transmission (ASK, FSK, BPSK, QPSK, and QAM), and extends to modern, spectrally efficient, digital communication techniques such as the asymmetric digital subscriber line (ADSL) and spread spectrum technologies (direct-sequence spread spectrum and frequency-hopping spread spectrum). This lab consists also phase-shift keying (PSK) circuit board for teaching method of digital communication in which the phase of a transmitted signal is varied to convey information. and the transmission lines circuit board to provide students with the theory and measurement skills required to implement and test communications transmission lines. Students first learn the principles and operational characteristics of transmission lines. They then learn how to conduct transmission line measurements under transient (step testing), and sinusoidal steady-state conditions. Finally, students acquire a valuable foundation in the theory and practice of time-domain reflectometry (TDR), as well as impedance matching and transformation.
