What do you call a circuit that changes a binary signal into decimal?

A circuit that changes a binary signal into decimal is referred to as a Binary to Decimal Converter. This type of converter takes binary digits (bits), which are typically represented as 0s and 1s, and transforms these values into their corresponding decimal representations.

The operation typically involves some form of arithmetic to interpret the binary number based on its positional notation. For example, the binary number 1011 would be calculated by multiplying each bit by its corresponding power of 2 and summing the results, resulting in a decimal value of 11.

Understanding this conversion process is fundamental in digital electronics, as binary is the base system for most digital devices, while decimal is the numeral system used in everyday human number representation. This bridge between the two systems allows for more intuitive interpretations of binary data.

Other options listed do not relate to this specific function. Analog Signal Processors deal with analog signals rather than binary data, Digital Multipliers perform functions related to multiplying binary numbers, and Signal Oscillators generate oscillating signals but do not perform any form of numerical conversion. Therefore, the Binary to Decimal Converter is the appropriate designation for a circuit with this specific capability.
