What kind of a semiconductor is widely in integrated circuit electronics?
A uniformly doped abrupt p-n junction (step junction) diode is fabricated. At room temperature 25% of the total space charge region (depletion region) is in the p region. The built in potential is also measured to be 0.710V.
The objective of this laboratory is to study and implement speed control of a dc motor.
3. Which of the following is not an advantage of FETs over BJTs in RF amplifier usage. A) Their input impedance does not load down the Q of the circuit preceding the FET stage. B) The availability of dual gate FETs provides an isolated injection poin..
A 3-phase delta/star transformer is supplies 6000 V on delta connected side. The terminal voltage on the secondary side when supplying full load at 0.8 lagging power factor is 415 V. The equivalent resistance and reactance drops for the transforme..
Find the system transfer function H(s) = Y(s)/X(s) if the input x(t) and the output y(t) of the system are related by the equation y(t) + 3y(t) = x(t) - x(tau)d tau. Assume y(0) = 0.
A step down chopper is to be used to supply power from 600 overhead wire to commutator motor on a trolley bus . The motor may be modeled as a generated direct voltage in series with a resistance of .2? and inductance of 25mH.
Typically a speech signal that can be understood over a telephone shows frequencies from 100 to 5 Khz. What would be the sampling frequency fs(sample/sec) what would be used to sample speech without aliasing.
The following represent solutions of the transmission line differential equations for some arbitrary function f(u): V(z,t) = 60 cos(1000t -5z) - 120 pi f (2t + z/100+12) V I(z,t) = 2 pi f (2t +z/100 +12) - cos (1000 t -5z) A a) what is the forward pr..
determine whether the statements are valid or invalid. If a statement is valid, please give a proof as in problem 1. If a statement is invalid, you need only provide a counterexample. If x + y = x + z, then y = z
find all minimum sum of products expressions. ( if there is more than one solution ,the number of solutions is given in parentheses.) label the solutions f1,f2.... a) f(w,x,y,z)= Σm(1,3,6,8,11,14)+Σd(2,4,5,13,15)
Write a 68000 assembly program to calculate the closest integer cubic root of a 16-bit signed number, saved in memory at a location labeled "NMBR". Obligatory Note: Use the subroutine concept in your solution
Design a diode voltage regulator to supply 1.5V to a 150-ohm load. Use two diodes specified to have a 0.7-V drop at a current of 10mA. The diodes are to be connected to a +5-V supply through a resistor R.
