A digital multiplexer is a combinational circuit that selects ________

1.	A digital multiplexer is a combinational circuit that selects ___________(a) One digital information from several sources and transmits the selected one(b) Many digital information and convert them into one(c) Many decimal inputs and transmits the selected information(d) Many decimal outputs and accepts the selected informationThis question was addressed to me during a job interview.This question is from Multiplexers (Data Selectors) topic in chapter Combinational Circuits of Digital Circuits
Answer» Right answer is (a) One digital INFORMATION from several sources and transmits the selected one The explanation: A digital multiplexer is a combinational circuit that SELECTS one digital information from several sources and transmits the selected information on a single output LINE depending on the status of the SELECT lines. That is why it is also known as a data SELECTOR.
