Design and implement a sequential circuit that counts from 0-3
in a repeating cycle with two inputs: step and reset. If the step
input is 1 the count progresses to the next value, if 0 you stay at
the current value. If the reset input is 1 the count returns to 0,
if 0 it has no effect. If both step and reset are 1, reset takes
precedence.
Use J-K flip flops in your design and follow the design process...
Question 3:
A)Design a BCD counter.
-The circuit counts from 0 to 9, then resets back to 0 to
restart the counting sequence.
-The circuit has one input run/stop. If the input is 1, the
eounter will count. If the input is 0, the counter will freeze in
its current location until the input is set to 1 again.
-The circuit has one output. It becomes 1 when the counter
completes a cycle and starts the next one. Otherwise, that...
You are an engineering consultant hired to verify an elevator
design. The elevator mass is 500kg and has a maximum occupant
capacity of 800kg. Carbon steel cables with total cross sectional
area of 64cm2 support the elevator. The maximum speed of the
elevator is 2 meters per second. At the maximum speed, each cable
extends at least 4 meters and cannot extend more than 22 meters,
unstretched. When the car is not moving and the cables are extended
by 22...
Three capacitors are arranged as shown as a portion of a
complete circuit. ?2 and ?3 are wired in parallel, and then the
system of (?2 + ?3) is wired in series to capacitor ?1. The
capacitances of each capacitor are ?1 = 5.1 ??, ?2 = 4.8 ??, and
C3= 6.2 ??. There is an unknown potential difference between points
a and b. a. What is the equivalent capacitance of the system? b. If
the charge on ?2 is...
Problem 3.73 (1-bit full adder using carry lookahead – gate
level circuit)
3.73 Design a 4-bit full adder using carry
look-ahead rather than ripple carry.
Q2.Find the equivalent circuit from no - load and short -
circuit test of a 3 - phase. 14.92 kW, 400 V, 6 - pole induction
motor from the following test results (line values): No - load: 400
- V, 11 A, p.f. = 0.2 Short - circuit: 100 - V, 25 A, p.f. = 0.4
Rotor Cu loss at standstill is half the total Cu loss.
3. Design and draw a circuit using the cascade system to operate
two cylinders (A and B) which, on the operation of a start valve,
produces the sequence A – B + B – A+. The cylinders should park in
the positions B – A + when the start switch is in the ‘off’
position.
4. Modify the circuit designed for question 3 to provide an
emergency stop which will park both cylinders in the extended
position (i.e. A +...
An elevator is hanging from a strong cable. The elevator is at
rest. Compare the force exerted by the cable on the elevator to
that exerted by the elevator on the cable. Also, compare the
tension in the cable to the weight (mg) of the elevator.
The elevator begins accelerating upwards. Make the same
comparisons.
The elevator begins descending at constant velocity. Make the
same comparisons.
Design a “disk spinning” animation circuit for a CD player. The
input to the circuit will be a 3-bit binary number A1, A2, A3
provided by 3-bit up counter. The circuit for 3-bit counter has
already been provided in CCT file on Google Classroom, so there is
no need to design the up counter yourself.
The animation will appear on the top four lights of the LED display
of Figure, i.e., on X1, X2, X7, and X6, going clockwise as...
