A home entertainment center has four different audio sources that can be played over the same set of speakers. Each audio source, named A,B,C,D, is connected using 8 wires on which the digitizedaudio signal is transmitted. The user selects which audio source is to be played using a rotary switch with 4 inputs, S0, S1, S2, S3, of wich exactly one will be '1'at any given time. If s0 = '1', the audio source A should be played if s1 = '1', the audio source 'B' should be played, and so on. Create a digital circuit with a single 8 bit output 0 that will output the users selected audio source.
