Optical Fiber Transmission Trainer TCM 001-12M
Digital Communication refers to the field of study concerned with the transmission of digital data. In contrast with analog communications, a digital transmission can be broken down into discrete messages.
Item Description
Transmitting data in discrete messages allows for greater signal processing capability. The ability top process a communications signal means that errors caused by random processes can be detected and corrected…..can also be sampled instead of continuously monitored and multiple signals can be multiplexed together to form one signal.
Different techniques of Digital communications can be understood by working on these kits that are accompanied with detailed student manuals. Circuit diagrams, inscriptions and legends printed on the pcb facilitates understanding the circuitry better and faster. Test Points are provided to analyze signals at different stages.
