1) Single-Ended signaling 2) Differential Signaling
single ended scsi is a method of transmitting electrical signals over wires. one wire carries a varying voltage that represent a signal, while other wire is connected to a ground. single emded scsi cables are of 6m-1.3m long. Differential scsi is a method of transmitting information electrically by means of 2 complementary signal pairs sent on 2 separate wires.
General Signal ended in 1998.
Federal Signal Company ended in 1923.
Hall Signal Company ended in 1925.
Kambe Signal Stop ended in 1944.
Federal Railway Signal Company ended in 1908.
RS-449A is a standard for serial data communication that defines electrical characteristics and signaling for the transmission of data between devices. It provides a means for connecting computers and peripherals over a balanced, differential signaling method, allowing for greater distance and noise immunity compared to single-ended signals. RS-449A is often used in environments where reliable data transfer is crucial, such as in industrial automation or telecommunications. Its key features include support for various data rates and multiple signal lines for control and communication functions.
The peak output value in a double ended differential amplifier is double the peak output value of a single ended differential amplifier for the same input signal because there are two outputs, one being the normal output, and the other being the inverted output. Whatever the normal output does, the inverted output does, but with a reverse sign. As a result, if one output has a value of X, then then other output has a value of -X. If you compare the two outputs, then, the difference between them will be 2X, or double the value.
when differential signaling was first introduced you could not mix se and hvd devices because of the high voltage used in the hvd. since then a new signaling called lvd is used and it will allow you to use a se if you use the lvd/se mode.( p.1008 managing and maintaining your PC 5th edition)
Single ended is referred to converters with single switch topology. SEPIC has only one switch and hence named Single ended primary inductor converter. (Primary inductor because the inductor is charged during ON cycle of the switch) For example, There are double ended flyback topologies with two switches. It is named as double ended because it contains two switches.
