Unformatted text preview: TTL data book – Fan-out – Propagation delay – Noise margin – Power dissipation 3. Waveform of 3-input AND and OR gates Assume a 3-input AND gate with output F and a 3-input OR gate with output G. Inputs are A, B, and C. Assume that there is no propagation delay, show the signals (by means of a timing diagram similar to Lecture notes No. 1-12) of the outputs F and G as functions of the three inputs ABC. Use all possible combinations of ABC. 4. 4-input NAND and NOR gates (a) Show the circuit of a four-input NAND gate using CMOS transistors. (b) Repeat for a four-input NOR gate....
