A student has to use an appropriate number of (i) NAND gates (only) to get the output y_(1) (ii) NOR gates (only) to get the output y_(2) from two given input A and B as shown in the Fig. Identify the 'equivalent gate' needed in each case. Show how one can connect an appropriate number of (i) NAND (ii) NOR gates respectively in the two cases to gat the equivalent gates.
