Binary PAM (Pulse Amplitude Modulation) is a method of transmitting data by varying the amplitude of pulses. In binary PAM, two distinct amplitude levels represent the binary digits 0 and 1. This allows for efficient communication of digital signals over various media, such as electrical wires or optical fibers. The key advantage of binary PAM is its simplicity and ease of implementation. It requires less bandwidth compared to more complex modulation schemes, making it suitable for applications like digital communication systems and data transmission. However, it is also more susceptible to noise, which can affect signal integrity.
