7) (10 pts) (Floyd 6.28) The waveforms below are applied to 4-bit parity logic generator. Determine the output waveform in proper relation to the inputs. For how many bit times does even parity occur and how is it indicated? The timing diagram uses 8 bit times. Bit time A0 A1 A2 A3 8) (10 pts) (Floyd 6.31) For each 7-seg display/decoder below. Indicate which are faulty and which are operating correctly. If they are faulty, which segment is causing the fault.
