QAM/DQAM MODULATION TRAINER TCM 002 – 05
Recent advances in wideband communication channels and solid-state electronics have allowed scientists to fully realize its advantages and thereby helping digital communications grow quickly. Digital communications is quickly edging out analog communication because of the vast demand to transmit computer data and the ability of digital communications to do so.
With the help of ‘Sci-tech’ Advanced Digital Communication Trainer Kits, Series TCM 002 Series, accompanied with necessary signal generators on-board and built-in power supply, ample experiments can be performed using the exhaustive manual. Test Points to analyze different signals are provided in the kits.
