Question
Chapter 7, Problem 10P
Program Plan Intro
Timer:
- Timer is mainly used to keep an output ON for a specific length of time.
- It provides a preset delay to the control actions.
- In a timer, the output will be energized when the preset value becomes equal to the accumulated value.
- Three different types of timers include a Delay-OFF, a Delay-ON, and a Delay-ON-Retentive timer.
Timer OFF Delay (TOF):
- TOF refers to an off-delay timer.
- TOF counts the time-based intervals as soon as the instruction becomes false.
- Here, the output changes its state from high to low when the timer provides some time delay (instruction goes from ON to OFF state).
Explanation of Solution
b.
Given:
Consider the given conditions,
- Input = True
- EN = 1
- TT = 1
- DN = 1
Explanation:
- The input is true, so the timer immediately assigns the DN signal bits value as true.
- Since the input is received with true condition, the EN signal bit will become true...

Explanation of Solution
d.
Given:

Design a sequential circuit with two D flip-flops A and B, and one input x_in. When x_in
the state of the circuit remains the same. When x in = 1, the circuit goes through the state
transitions from 00 to 01, to 11, to 10, back to 00, and repeats.
3. Design a logic circuit that controls an elevator door in a three-story building. M is a logic signal
that indicates when the elevator is moving (M = 1) or stopped (M = 0). F1, F2, and F3 are floor
indicator signals that are normally LOW, and they go HIGH only when the elevator is positioned
at the level of that particular floor. For example, when the elevator is lined up level with the
second floor, F2 = 1 and F1 = F3 = 0. The circuit output is the OPEN signal, which is normally
LOW and will go HIGH when the elevator door is to be opened. We can fill in the truth table for
the OPEN output as follows:
a. Because the elevator cannot be lined up with more than one floor at a time, only one of
the floor inputs can be HIGH at any given time. This means that all those cases in the
truth table where more than one floor input is a 1 are don't-care conditions. We can
place an x in the OPEN output column for those eight cases where more than one F
input is 1.
b. Looking at the other eight…
A sequential circuit has three flip-flops A, B, C; one input, x; and one output y. The state diagram is shown in Fig. P6-22. The circuit is to be designed by treating the unused state as don't - care condition. The final circuit must be analyzed to ensure that it is self correcting.
(B) Use JK flip-flops in the design

M is a logic signal that indicates when the elevator is moving (M=1) or stopped (M=0). F1, F2 and F3 are floor indicator signals.

For an example, OPEN is HIGH when the elevator is not moving (M=0) and lined up with the second floor, F2=1, while not lined up with others (F1=F3=0). Also remember that the elevator cannot be lined up with more than one floor at a time, as only one of the floor inputs can be HIGH at any given time.arrow_forward
