Figure 1 shows the digital logic diagram. (a) Express A, B, C3 and Y in terms of the inputs X1,X2 and X3. (b) If the input hit streams of X1,X2 and X3 are found in T2ble 1 . Assume the bit streams of XI,X2 and X3 change at the same instance for every digit. Find the output bit stream of the circuit by completing rows A,B and C in Table L. (c) Sketeh the waveform of Y aceording to the imputs provided in X1,X2 and X3
