Question 3 Not yet answered A 4-variable logic function Y (A3, A2, A1, Ao) is implemented using a 4x1 multiplexer (4x1 MUX) and some external gates as shown in the circuit diagram that follows. If the waveforms for all inputs are given as shown in the timing diagram below, then the output waveform for Y can be: Marked out of 5.00 4x1 MUX Flag question A. A A2 .
