• It is normal for more than one decoder output to be active at the same time.
• In HDL, a process is usually thought of as a wire connecting two points in a circuit.
• When data input I1 of a 74148 octal-to-binary encoder is active, the data output is: A0 = 0 A1 = 0 A2 = 1
• Basically, a multiplexer changes parallel data inputs to a serial output.
