Consider a 4-bit counter made with JK flip-flops with preset and clear inputs. Describe the changes/additions that need to make the counter reset after counting to 1001. Be sure to state any assumptions that are made. Explain how recirculating shift registers work and name at least one function that they may be used for.
A 3-phase, 200 hp, 480 V, 6 pole, 60 Hz synchronous motor has asynchronous reactance x1= 1.5Ω and x2=1.5Ω. Neglect all losses. The motor is connected to an infinite bus, and it delivers its rated horsepower at unity power factor.
Design a one-op-ampactive band pass filter that has a midband (at 5 KHz) inputimpedance of approximately 10K, a midband gain of approximately 1and a frequency response from 1 to 10KHz(corner frequencies).Verify by computing the circuit frequency r..
a digital channel is described by 16 QAM, the data rate is 50 Mbps, the bandwidth is 200 MHz, the power is 1 W, and the received noise level is 50 mW. Resolve for SNR, Baud Rate and the Max theoretical bit rate for the channel.
A 40 H resistor, a 5 mH inductor, and a 1.25/xF capacitor are connected in series. The series-connected elements are energized by a sinusoidal voltage source whose voltage is 600 cos (8000t + 20°)V. a) Draw the frequency-domain equivalent circuit.
Consider a product data sheet for a photo-detector that states an optical power level of -32dbm is need at the photo-detector to specify performance requirement. What is the power level nW (nano Watts)
a) Evaluate % overshoot, settling time and peak time if a=4 and b=25 b) Calculate values of a&b so imaginary part of poles remains same but real part increased by 2 times
Each single phase transformer has an identical number of turns in the primary and secondary windings. If a line-to-line voltage of 480V is applied on the wye windings, compute the line-to-line voltage on the delta windings.
The battery is made by connecting 7 unit cells in series and then by connecting 5 of these series cells in parallel. Each unit cell has the voltage of 1.25 V and the internal resistance if 3.2 Ohm. What is the maximum power that can be delivered t..
a. What is the expected amplification of a BJT transistor amplifier if the dc supply is set to zero volts. b. What will happen to the output ac signal if the dc level is insufficient.
Assume that the basic inverter has (W/L)n = 0.5 um/0.25 um and (W/L)p = 2 um/0.25 um. What is the minimum area occupied by the circuit neglecting contact areas. Assume that the inputs A and B and their complements are available.
The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 50o; then it is commanded to go to 15o. When the error is 10o for the first time, what is direction of the robot arm
a half wave rectifier circuit with a 1K ohm load operates from a 120V rms 60-Hz household supply through a 10-to-1 step down transformer. It uses a silicon diode that can be modeled to have a 0.7V drop for any current.
