The Hong Kong University of Science and Technology Department of Electronic and Computer Engineering ELEC151 – Digital Circuit and Systems Homework 5 Issue Date: 23-10-2008 Due Date: 31-10-2008 5:00pm *** Except the parts require computer plot, you need to do the homework by hand . *** Please put your assignment into the collection boxes labeled “ELEC151” outside the ECE Departmental General Office, 2 nd Floor, near Lift 25-26 (Outside Rm. 2513). 1. The D latch of Fig.5-6 is constructed with four NAND gates and an inverter. Consider the following three other ways for obtaining a D latch. In each case, draw the logic diagram and verify the circuit operation. a) Use NOR gates for the SR latch part and AND gates for the other two. An

Unformatted text preview: inverter may be needed. b) Use NOR gates for all four gates. Inverters may be needed. 2. (a) Construct a JK flip-flop, using a D flip-flop, a 3-8 decoder, and a OR gate (b) Construct a JK flip-flop, using a D flip-flop, a two-to-one line multiplexer, and an inverter. 3. Design an edge-triggered D flip-flop with Reset function by NOR gates - On Note 5-34 is a D flip-flop with Reset function by NAND gates - On Note 5-20 is a D flip-flop without Reset function by NOR gates 4 Design a master/slave D flip-flop with Reset function by transmission gates - On Note 5-41 is a master/slave D flip-flop without Reset function by transmission gates...
