A digital current loop uses the absence of current for high (space or break), and the presence of current in the loop for low (mark). [1] This is done to ensure that on normal conditions there is always current flowing and in the event of a line being cut the flow stops indefinitely, immediately raising the alarm of the event usually as the heavy noise of the teleprinter not being synchronized ...
The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems.
DCB Interface. DCB (Digital Control Bus, Digital Connection Bus [1] or Digital Communication Bus [2] [3] in some sources) was a proprietary data interchange interface by Roland Corporation, developed in 1981 [3] and introduced in 1982 in their Roland Juno-60 and Roland Jupiter-8 products. [3]
Jawaharlal Nehru Technological University, Anantapur (JNTU Anantapur) is a state university in Anantapur, Andhra Pradesh, India. Founded in 1946, it has since 1973 been a constituent college of Jawaharlal Nehru Technological University , [ 1 ] as set by The Jawaharlal Nehru Technological University Act, 1972 . [ 2 ]

Two-wire circuits in new installations are limited to intercom and military field telephone applications, though these too are being supplanted by modern digital communication modes. To communicate in both directions in the same wire pair, conversion between four-wire and two-wire was necessary, both at the telephone and at the central office .
It enables a secure serial digital communication between controller, sensor and actuator. The BiSS protocol is designed in B mode and C mode (continuously bidirectional mode). It is used in industrial applications which require transfer rates, safety, flexibility and a minimized implementation effort.
In signal processing, a root-raised-cosine filter (RRC), sometimes known as square-root-raised-cosine filter (SRRC), is frequently used as the transmit and receive filter in a digital communication system to perform matched filtering. This helps in constraining the occupied bandwidth of the waveform without introducing intersymbol interference ...
