RS-Flip Flop

Realize the R-S ip op function by using NOR gate ONLY,

with trigger/clock signal added. (NOTE: This exercise is to show that a NAND gate can

be realized by using NOR gates. The reverse is also true).

(

Hint: You may follow the steps as below: 1) Find the logic expressions for Q, and Q

,

respectively (according to the logic circuit, as here only two stages are involved, Karnaugh

map may not be necessary); 2) Realize the two logic expressions by using NOR gates|De

Mogan's law will be useful here.)

Explanation / Answer

Transistor NOR Gate

A simple 2-input logic NOR gate can be constructed using RTL Resistor-transistor switches connected together as shown below with the inputs connected directly to the transistor bases. Both transistors must be cut-off
