Question 1
1.1 The following waveforms are applied to the DIV 16 counter. Sketch the output
waveforms (Q0 Q1 Q2 and Q3) in relation to the inputs. The clear input is
asynchronous.
1.2 Draw a complete timing diagram for a 3-bit u(p)/(d)own counter that goes through the
following sequence. Indicate when the counter is in the UP mode and when it is in th
DOWN mode. Assume positive edge-triggering.
0,1,2,3,2,1,2,3,4,5,6,5,4,3,2,1,0
1.3 Design a synchronous counter to produce the following binary
sequence. Use J-K flip-flops. Use the answer sheet.
0,9,1,8,2,7,3,6,4,5,0,
