Electrical, Computer, & Telecommunications Engineering Technology Digital Fundamentals 20072 0618-301 HW #8 HW #8 Due 2/21/08 1. Read Chapter 6: section 1 (skip example 6.2 and section 6.1.2) Section 2 Section 3 2. The circuit below shows how an eight-input MUX can be used to generate a four-variable logic function. Complete the four-variable truth table for this function, showing the output Z for the 16 possible combinations of input variables. 3. Using an 8–to–1 mux like the one in problem 2, implement the following function: ܼ ൌ ܦ ܤ ܥ ҧ ܣ ൅ ܥ ҧ ܤܣ ൅ ܦܥܤ ܣ ൅ ܥܤܣ

The circuit below shows how a multiplexer can be used to generate logic waveforms with any desirable pattern. The pattern is programmed using eight switches and the waveform is repetitively produced by pulsing the MOD-8 counter. Draw the waveform at Z for the given switch positions. 5. Textbook problem 6.1 (Look at example 6.25 on pg. 364 for hints) 6. Textbook problem 6.2 7. Show how to use two 3-to-8 decoders to make one 4-to-16 decoder....
