Nyquist data sampling rate in pulse code modulation (PCM).
The Nyquist data sampling rate in pulse code modulation (PCM) is twice the highest frequency component in the original analog signal. This means that the sample rate must be high enough to accurately capture all the details of the original signal. According to the Nyquist theorem, the minimum sampliRead more
The Nyquist data sampling rate in pulse code modulation (PCM) is twice the highest frequency component in the original analog signal. This means that the sample rate must be high enough to accurately capture all the details of the original signal. According to the Nyquist theorem, the minimum sampling rate required to avoid aliasing (the phenomenon where high-frequency components in the original signal are misinterpreted as low-frequency components in the sampled signal) is twice the highest frequency component in the original signal.
In PCM, the analog signal is sampled at regular intervals, and each sample is quantized and encoded into a digital value. The quantization step determines the number of bits used to represent each sample, and thus the dynamic range and accuracy of the digital representation of the analog signal. The Nyquist rate determines the minimum number of samples required to accurately represent the original analog signal in the digital domain.

Data Terminal Equipment (DTE) refers to the devices that generate, process, and use data, such as computers, terminals, printers, and modems. DTE typically initiates a communication session and is the source or destination of data in a communication network.
Data Communication Equipment (DCE) refers to the devices that provide a physical connection between DTE devices, enabling them to exchange data. DCE devices typically include modems, routers, switches, and multiplexers. They provide the physical and data link layer services required to transmit data between DTE devices.
In a data communication system, the DTE device communicates with the DCE device, which in turn communicates with other DCE or DTE devices. The DCE provides the interface between the DTE and the communication network, such as a telephone or an Ethernet network, and is responsible for converting the data generated by the DTE into a format suitable for transmission over the network.
