Objective:
The objective of this assignment
is to prepare students to familiar with concepts of flip flops, counters and
particularly working of up/down counters. Furthermore it will enhance one’s
ability to differentiate the operations of different types of counters.
Statement
Sketch the timing diagram against Q0, Q1, Q2 and
Q3 and determine the counter
sequence of a synchronous 4-bit binary up/down counter if the clock and UP/
control inputs have waveforms as shown in figure below. The
counter starts in the all 0s state and is positive edge triggered. 
control inputs have waveforms as shown in figure below. The
counter starts in the all 0s state and is positive edge triggered.
