You have a 10 microfarad capacitor that has resonance at 1MHz.
1) Plot the impedance with respect fo frequency from 1Hz to 10MHz
2) Capacitor must be less than .1 of a 480 ohm resistor to be a good bypass capacitor for that resistor. What range of frequencies can we use this capacitor for?
A 9.2 kg crate is pulled up an incline with initial speed of 1.2 m/s A pulling force of 105N is applied parallel to surface of incline which is at angle of 21.8 degrees to horizontal The coefficient of kinetic friction is .32 and crate is pulled d..
What is the peak frequency deviation of the FM signal? What is the FM improvement in dB?
1- Find the voltage across the inductor for t > 0 2- Sketch the voltage and the current as a function of time 3- Find the power ( in microwatts) at the terminals of the inductor when t = 200 ms
Attenuation of received power with change in transmission frequency and distance between the antennas
Assume that h is a random variable with PDF. Pn(h)=0.1*d(h-1)+0.9d(h-3). n is a zero mean white gaussian noise with variance 0.5. Assume that the channel state info is available at the reciever for each of the three branches.
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
Design a simple unipolar drive circuit such that the electrical time constant is 2 msec at phase turn-on and 1 msec at turnoff. The stepping rate is 300 steps per second. A three-phase variable-reluctance stepper motor has parameters.
Vo(t) = RC (dVi(t)/dt). Suppose you have a triangle waveform as input to the differentiator with 100pF capacitance and 100 Ohms. The peak to peak voltage of the triangle waveform is 10Vpp and its frequency is 100k Hz.
Give a narritve for a cruise control system of a car. Include all relevant inputs and outputs. Design a flowchart and ladder diagram. Every element on the ladder diagram must be labelled and described.
Determine the surface charge density on each conductor.
Assume that an additional inductance can be inserted in series with the load. also assume that the converter has no freewheeling diodes. Calculate the added inductance that leads to a conduction period of 180 degrees when alpha = 30 degrees.
Optimum length of the antenna to receive the FM station, An FM radio station transmits at a frequency of 99.9 MHz. A radio receiver has an antenna that is a quarter wavelength monopole consisting of a telescoping rod
