1) How do you find the calculus, the derivative and integral of a sinewave? 2) How do you show that a triangle wave can be obtained from a square? 3) What is the inverse of dSQ/dt?
The normalized lowpass filter with a cutoff frequency of 1 rad/sec is given as Hp(s) 1/s+1 a. Use Hp(s) and the BLT to obtain an corresponding IIR digital high passs filter with a cutoff of 30 Hz, assuming a sampling rate of 200 hz,
The motor driven by a switch-mode dc-dc converter, which has a bus voltage of 200V. The switching frequency fs = 25 kHz. Calculate and plot the waveforms for va(t), ea(t), ia(t), and id(t) under the following conditions
A fluorescent tube fixture takes 1 ampere when connected to a 120-volt source. A wattmeter in the circuit reads 80 watts. What is the' operating power factor of this unit
Write a program that uses the rand_float functions developed to generating sequences of random floating-point values between 4 and 10. Then compare the computed mean and variance to the theoretical values computed.
A signal contains a mixture 30 , 100 and 240 Hz Sine waves and also contains wideband noise whose spectrum is from 500 Hz up to a 1000 Hz. Describe a filtering technique that can be used to cleanly separate 30, 100 and 240 Hz from each other and a..
A 25MVA, three phase, 13.5kV, Y-connected, two pole, 60Hz synchronous generator was tested by the open circuit test and short circuit test and tabulated in table 1. If the armature resistance is 0.24 ohms per phase.
Sketch the equivalent circuit and phasor diagram for the no-load conditions and, assuming operation is in the step down mode, determine (a)the exciting current; (b)the core loss component of the exciting current; (c)the magnetizing current; (d)the..
In a piezo electric accelrometer circuit which is being used to find out the effect of load capacitance a coaxial lead is used instead of a normal 'unshielded' wire, why is a coaxial lead used
First as the output stage use a Zener shunt regulator and then replace the Zener shunt regulator with an appropriate IC voltage regulator. Do the SPICE simulation of the whole circuit, which has the Zener shunt regulator as the last stage.
A body attached to earth ground by an electrical conductor is at zero electrical potential. A charge of 25 C is added to the body. What is the potential of the body now. Explain.
Suppose an 802.11b station is configured to always reserve the channel with RTS/CTS sequence. Suppose this station suddenly wants to transmit 1,000 bytes of data, and all other stations are idle at this time. Suppose the transmission rate is 11Mbp..
the input voltage to an op amp is a large voltage step. the output is a exponential waveform that changes 2.0V in 0.4us. what is the slew rate of the op amp.
