Fig. I: a mod-Iv eoune 3. About SRG, please answer the following questions. a) How many 74HC195 (see Fig. 2) do you need for designing a mod-26 Johnson counter?(396) (b) F or a mod-6 Johnson counter, please write out its counting sequence (note: using decimal value). (6%) c) Consider the example using the output Q2 of 74HC195 to provide time delay. If the clock frequency is 100 Hz, what is the time delay? (3%) d) Consider the example using the output Qo of 74HC195 to provide time delay. If we want to get a time elay 10 msec, what is the clock frequency?
