Understanding Biphase Signaling: Principles and Applications

Biphase is a type of signaling that uses two different phase states to transmit information. It is commonly used in digital communication systems, such as serial communications protocols like RS-232 and RS-485.

In biphase signaling, the signal is transmitted by switching between two distinct phase states, typically represented as 0° and 180°. The receiver detects the transitions between these phase states to determine the information being transmitted.

Biphase signaling is simple and easy to implement, but it has limited bandwidth and can be susceptible to noise and interference. It is often used in applications where high data rates are not required, such as in industrial control systems or home automation networks.
