The source-free circuit is constructed using a 10mH inductor, a 1mF cPcitor, and a 1.5k ohm resistor.a) Calculate alpha, omega-sub-delta, and omega-sub-zero.b) write the equation which describes the current i for t>0.c) determine the maximum value of i, and the time at which it occurs, if the inductor initially stores no energy and v(0-)=9V.
design a sequential circuit that continuously computes the function 2X + 3 or 3X + 1 where the variable X is a three-bit unsigned integer available on a serial interface. A special external data signal (DATA_READY) is asserted
During a walk at the park we spot blue birds and red birds. Suppose each red bird with probability 3/4 and blue birds with probability 1/4. (a) In a collection of 5 randomly selected birds, what is the probability that none are blue
Write a brief explanation of the principles of the super-heterodyne receiver. It may help to use a simple block diagram to express the process. Explain the purpose of the Intermediate Frequency amplifiers,
1) For a forwarard converter, derive the minimum value of Vr - as a function of the input voltage Vg, the duty cycle D, and the turns ratio N1/N2 - that will cause the transformer magnetizing current to be reset to zero by the end of the switching..
Consider a system equation \(s^{4}+s^{3}+s^{2}+2s+10=0\) Find its Routh Table. Determine if the system is stable , marginal stable, or unstable.
A loop of current is placed in the xy plane in a uniform magnetic field in the positive x direction. If the current in the loop is in the clockwise direction, what is the direction of the torque on the loop
In most situations it is also desirable to send information from the process to be controlled--in this case the 500-gallon tank--to a central station for processing and storage. This information can be transmitted and processed in different ways.
a DC shunt machine ( 24kW, 240V, 1000 RPM) has Ra= .12 ohms, Nf= 600 turns/pol. The machine is operated as a seperately excited dc generator and is driven at 1000 RPM. When If = 1.8 amps the no load terminal voltage is 240V.
Consider a regenerative Rankine cycle with a 600_C and 4-MPa throttle, a 5-kPa condenser, and an open feedwater heater at 500 kPa. Turbine efficiencies are 85%. Neglect pump work. (a) Draw labeled, coordinated T-s and flow diagrams.
Suppose a constant force of kinetic friction acts between the block and the surface, with k = 0.53. If the speed of the block at the moment it collides with the spring is vA = 1.4 m/s, what is the maximum compression xC in the spring
Explain what the cumulative probability distribution function indicates in this case. If the rms value is given by 2 sigma, compute the percentage of time that a signal is 12 dB or more below the rms value for a Rayleigh fading signal.
1. A signal with a range of 0-12 V is sampled with an 8-bit ADC. What is the change in voltage (delta) between digitized levels 2. Using the SPI, we send three bytes to the LTC2600 DAC. What information is provided in each of the three bytes
