Question

The data processor function of a PCM receives the data from the input signal processing section and compares it to ________ in the memory

Answer 1

In a PCM system, the data processor compares the input signal data to a reference signal or quantization levels stored in memory to encode it into a digital signal.

Step-by-step explanation:

The data processor function of a PCM (Pulse Code Modulation) system receives data from the input signal processing section and typically compares it to a reference signal stored in the memory. This process is part of the quantization step in PCM where the amplitude of the analog signal is approximated to the nearest value represented by a binary code. A PCM encoder will compare input signal samples with a set of predetermined levels or a quantization scale to determine the closest match, which is then encoded into a digital signal.

Answer 2

The data processor function of a PCM receives the data from the input signal processing section and compares it to Standardized Data in the memory

Step-by-step explanation:

PCM processor is the device that is used in the automobiles to analyze the performance of the engine. It works like the brain of the computer. Whenever user starts the vehicle, this processor retrieve the input from all the sensors installed in the vehicle. This input data is compared with the standardized information stored in the memory. The input data has been analyzed as per standardized information and generate alerts in case of any system failure or fault.

Standardized data is the data that is set used as threshold value that is used to compare with the input data. If input data is according to the standardized data it means there is no error in the system.
