If one of the normal vectors to an interface is n-hat = 1/sqrt(13) (3x-hat + 2z-hat) and the electric field just below the interface is E1 = 9x-hat + 2y-hat + 2z-hat, what is the vector part of E1 normal to the interface?
Calculate the current in the output of the source before and after the installation of the new device and The temperature sensor output is a voltage which is equal to the temperature sensed by the sensor. Design an electric circuit which can get th..
write an 8051 program that would generate a 200khz, 50% duty cycle, square wave at P1.0.Use Timer 0 for the delay. Ignore the overheads cycles due to the instructions in the loop. Assume 12 MHz clock. All data must be hex.
What is the BER at the output of the receiver in clear air conditions, and the average time between errors? Give your answer in years, days, or hours as appropriate. Assume an implementation margin of 0.5 dB.
Write a brief explanation of the principles of the super-heterodyne receiver. It may help to use a simple block diagram to express the process. Explain the purpose of the Intermediate Frequency amplifiers,
Flux weakening causes problems in both generators and motors. In generators, the effect of flux weakening is simply to reduce the voltage supplied by the generator for any given load. In motors, the effect can be more serious.
An 8 bit shift register is configured so that the output of the least significant bit is fed back to the input of the most significant bit. If the register has an initial state of 11010001, what does the shift register contains after three clock p..
What would be the minimum allowable sampling rate for a pulse-duration modulator if it is required to handle a baseband frequency range from 50 Hz to 10 kHz
How many decimal numbers can be represented by 8-bits. What is the largest positive signed decimal number that can be represented by 8-bits.
phosgene ccl2o is a colorless insidious, highly toxic gas which has been used as a war gas and is sometimes used in the preparation of organic chemicals. draw the lewis structure for phosgene ( Cis the central atom)
A synchronous generator is rated 1,300 MVA, 22,000 volt, three phase, 3600 rpm, 60 Hz with a synchronous reactance of 0.35 ohms per phase. The machine is delivering rated output at rated voltage and 0.94 power factor lagging.
Resistance=0.09ohm/km Inductance=1.4mH/km Capacitance=8.8x10-3 uF/km. Calculate the sending-end power if the receiving-end voltage is 132kV and the receiving-end power is S2=100+j60 MVA. Assume a pi-equivalent circuit.
The common crystal used in older color teleisions outputs a 3.58002 MHz signal. What is the MOD number required for a counter to reduce this to a 60Hz output
