Nand Gate

NAND and NOR gates are called universal gates because they

Assertion: NAND or NOR gates are called digital building blocks. Reason: The repeated use of NAND (or NOR ) gates can produce all the basic or complicated gates.

Write logic symbol boolean expression and truth table of NAND and OR gate

Symbolic representation of four logic gates are shown as (i) Pick out which ones are for AND, NAND and NOT gates, respectively.

Symbolic representation of four logic gates are shown as: Pick out which ones are for AND, NAND and NOT gates, respectively

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.

A NOR gate and a NAND gate are connected shown. Two different sets of inputs are given to this set up. In the first case, the inputs to the gates are A = 0, B = 0, C = 0. In the second case, the inputs are A = 1, B = 0, C = 1. The output D in the first case and second case respectively are
