The voltage across a 1x10^(-6)F capacitor is given by v(t)=100e^(-100t) in which time t is in seconds.
1. find an expression for the current
2. find an expression for the power
3. find an expression for the stored energy
Determine the fundamental frequency w0, the period t0, and the coefficients in the representation X(t) = x0 + Re{k=1N Xkejkwot} for the above input. Remember, you can do this problem without evaluating any integrals.
determine the transfer function of a 4th order lowpass butterworth filter with a 3-dB cutoff frequency of 3.4 kHz and passband gain=1. Design the circuit using MFB topology. Design two sections with an order of 2.
An AC sine wave is applied to the input of a full wave rectifier. The output of the full wave rectifier is then applied to a half wave rectifier.
1.Calculate motor speed in revolutions per minute for an eight-pole,50Hz motor. Give the equation and identify its parts; show your math. 2.You need to detect finished products coming down an assembly line.
A certain three-port network is lossless and reciprocal, and has S13 = S23 and S11 = S22. Show that if port 2 is terminated with a matched load, then port 1 can be matched by placing an appropriate reactance at port 3.
What is the equivalent input noise resistance of an amplifier known to produce 20 V of equivalent input noise over a bandwidth of 750 kHz
determine the corediameter required for the fiber topermit its operation over the wavelength range 1.48 to 1.60um. calculate the new fiber core diameter to enable single mode transmission at a wave length of 1.30um.
Develop with MATLAB, a fuzzy control system for controlling the power of a motor (0-350 rpm) based on the supported load (0-1700 lbs) thereby that at greater load develops more power. The system must contain at least 5 rules, but preferably 7.
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
What is the requirement for the phase response (transfer function) of each of these links to avoid distortion of the transmitted waveform?
A 3-D cubic unit cell contains four atoms whose centers are positional halfway up along each of the vertical cell edges and one atom each centered in the middle of the top and bottom faces.
The U.S. Digital Cellular provider uses a TDMA scheme for multiple access. It uses a 48.6 kbps data rate and supports three users per frame. Each user occupies two of the six time slots per frame. Compute the raw data rate provided for each user.
