A single phase full bridge inverter feds power at 50Hz to RLC load with r=5 ohms , l=0.3H and C=50μF. The dc input voltage is 220volts. (a) Find an expression for load current up to fifth harmonic (b) Calcute the power absorbed by the load abnd the fundamental power (c) rms and peak currents of each thyistor(d) conduction time of thyristor and diodes if only fundamental component were considered.
In a particular technology, a small BJT operating at vBE = 28VT conducts a collector current of 100µA. What is the corresponding saturation current. For a transistor in the same technology but with an emitter junction that is 32 times larger
A sensor with a nominal resistance of 50 ? is used in a bridge with R1 = R2 = 100 ?, V = 10.0 V, and R3 = 100 potentiometer. It is necessary to resolve 0.1 changes of the sensor resistance. A) At what value of R3 will the bridge null
Four hundred grams of nitrogen gas (molecular weight=28g/mole) are stored in a 10-liter container. Set up an excel worksheet to determine the pressure of the gas (in atmospheres) as a function of temperature and volume, assuming nitrogen is an idea..
Two stages are cascaded to result in an overall gain of 680 V/V.The loaded gain of the first stage is 36 dB. What must the gain ofthe second stage be in dB to satisfy this specification In V/V
a). If the 8th bit is set to0, what is the minimum Hamming distance between the 8-bit ASCII character code words b). If the 8th bit is usedfor parity, what is the minimum Hamming distance between the 8-bitASCII character code words
Determine whether the discrete signals below are periodic. If the signal is periodic, determine the number of samples per period. (a) x[n]=cos(πn) (b) x[n]= -3sin(.01πn) (c) x[n]= 1+cos((πn)/2)
The voltage and current at the terminals of the circuit element are zero for t = 0 they are v = (10,000t+ 5)e^-400t V. and i = (40t + 0.05)e^-400t A. a) at what instant of time is maximum power delivered to the element
Write a program that reads a file containing only integer, but some of the integers have embedded commas, as in 145,020. The program should copy the information to a new file, removing any commas from the information.
What device can be used to connect to data bus with enable/disable capability. When all these kind of devices tied to the bus are disabled, what logic level is on the bus line.
a) Generate the State Transition Table, which should include the binary( ones and zeroes) values of the Flip Flop inputs which then enable you to determine next states based on current states. b) Draw the State Diagram for the system.
suppose that A/D-H(z)-D/A system shown uses a sampling rate of 20000 samples/sec , let xa(t)=10cos (2p*500t)u(t) a- give another input signal x1(t) which gives the same samples x(n) b- give another input signal x2(t)
