Quick Summary

Bit mapping is a process used in digital communications, particularly in analog-to-digital conversion. It involves representing analog signals, such as voice or video, as binary data, which consists of 0s and 1s. This conversion is essential because binary signals are more resistant to distortion and noise during transmission, allowing for more accurate reception.1

The process maps quantized signal levels into binary sequences. The number of bits required depends on the number of levels used; for example, 2ⁿ levels require n bits. This binary data can then be transmitted through communication channels. A bitmapped image or display is an array of binary data that specifies the value of each pixel.23
