As a domain expert, I specialize in the field of digital signal processing and communication systems. My expertise lies in understanding and explaining complex concepts such as Pulse Code Modulation, or PCM. Now, let's delve into the subject matter.
Pulse Code Modulation, commonly referred to as PCM, is a method used to digitally represent analog signals. It is a fundamental technique in the transmission of information, particularly in the realm of telecommunication and digital audio. The process of PCM involves several key steps, including sampling, quantization, and encoding.
Sampling is the first step in PCM, where an analog signal is sampled at regular intervals. This is done to convert the continuous analog signal into a discrete form that can be processed by digital systems.
Quantization follows sampling, where the sampled values are mapped to the nearest digital values. This step introduces some level of error, known as quantization noise, due to the approximation of the continuous signal values to a finite set of discrete levels.
Encoding is the final step, where the quantized values are encoded into binary form, creating a sequence of bits that represent the original analog signal.
The PCM process results in a series of binary digits, or bits, that can be transmitted over digital channels. The digital nature of PCM provides several advantages, such as the ability to be easily stored, processed, and transmitted without significant degradation, unlike analog signals which are susceptible to noise and distortion.
One of the critical aspects of PCM is its efficiency in terms of bandwidth usage. By using a limited number of bits for each sample, it optimizes the transmission of information, ensuring that the digital signal can be transmitted with minimal loss of quality.
Moreover, PCM is the foundation for many advanced digital communication systems and protocols. It is used in various applications, from traditional telephony to modern digital audio and video transmission.
In summary, PCM is a vital technique in the digital representation of analog signals, offering a reliable and efficient method for signal transmission and processing in the digital domain.

Pulse code modulation (PCM) is a digital scheme for transmitting analog data. The signals in PCM are binary; that is, there are only two possible states, represented by logic 1 (high) and logic 0 (low). This is true no matter how complex the analog waveform happens to be.
