The correct answer is:
(a) Analog to Digital converter
Explanation:
ADC stands for Analog to Digital Converter. It is a device that converts continuous analog signals (such as voltage) into discrete digital values, which can then be processed by digital systems like microcontrollers, computers, or digital signal processors (DSPs).
- (b) Discrete to Analog converter: This refers to a different type of converter, typically called a DAC (Digital to Analog Converter), which is not the correct choice.
- (c) Analog to Digital converter: This is the correct full form of ADC.
- (d) Discrete to Avalanche converter: This is not a recognized term related to ADCs.
Thus, the correct full form of ADC is Analog to Digital Converter, as given in option (a).
