The kilowatthour-meter of a home is read once a month. For a particular month, the previous and present readings are as follows:
Previous reading: 3246 kWh
Present reading: 4017 kWh
Calculate the electricity bill for that month based on the following residential rate schedule:
Minimum monthly charge-$12.00
First 100 kWh per month at 16 cents/kWh
Next 200 kWh per month at 10 cents/kWh
Over 300 kWh per month at 6 cents/kWh
Design a 2-stage voltage amplifier, the first stage a common-source and the second a source-follower. The load onthe S-F is 100 ohm, and the signal impedance is 1 K-ohm. The overall voltage gain should be -10 V/V. Use a single power supply, VDD = ..
A calorimeter contains 50 g of water at 50°C. The temperature falls to 45°C in 10 minutes. When the calorimeter contains 100g of water at 50°C, it takes 18 minutes for the temperatureto become 45°C. Find the water equivalent mass of the calorimete..
Compare the maximum theoretical PCE for 980-nm and 1475-nm pumping in an EDFA for a 1545-nm signal. Contrast this with actual measured results of PCE = 50.0% and 75.6% for 980-nm and 1475-nm pumping, respectively.
An LED is connected to a 74LS244 in an active-LOW configuration. The key parameters for the 74Ls244 are IOH=-15 mA, IOL=20 mA, VOH =2.0V and Vol=0.5V. The LED has a voltage drop of 2.0V and an operating current of 15 mA.
Design a four-bit shift register with a paralel load, usingD-flip-flops. There are two control inputs:shift and load. Whenshift t=1, the contents of the register are shifted by oneposition. New data are transferred into the register when load=1and..
The current in the bulb depends on the time t according to the relation I = (0.807 A) sin [(272 rad/s)t]. (a) What is the frequency of the alternating current (b) Determine the resistance of the bulb's filament. (c) What is the average power deliv..
One of the home satellite services uses a dish antenna having a diameter of 18" (0.457 m) and frequency of 12.45 GHz. If the illumination efficiency is 70%, determine the gain of the antenna in dB
Simulate the proportional fair scheduling algorithm for tc large and compute the performance of each user for a range of y from 1 to 100. You can assume the use of capacity-achieving codes.
Provide the state diagram b) Generate the truth table showing the previous state and input combinations, and next state and outputs. c) Encode the states and give the next state equations for the Q's and output as: - One hot encoding
how to connect two n channel mosfet and then how we can measure the surface potential between its common drain
Write the logic equation for Y in terms of A,B,C that solves this problem, and draw the gate-level diagram.
Given three induction motors, find the real power P, the reactive power Q, and the apparent power S for each motor. Alsofind P, Q, and S for the total motor load. Motor 1: draws an electrical power of 100kw with power factor=.90 lagging.
