a stereo reciver is tuned to 98 MHz on the FM band, the tuning knob conrols a variable capacitor in a parallel resonant circuit. inductance of the circuit is 2μH and the Q is 100, suppose that another FM station is in the vicinity is broadcasting at 98.1 MHz. determine the relative value of the voltage across the resonant circuit at this frequency compared with that at 98 MHz, assume that the current produced by both signals has the same amplitude.
Consider the convolutional code described by connection polynomials
An adiabatic piston cylinder contains 1 kg of R-134a. Initially the conditions inside the piston are 200 kPa and 0 degrees C. An electric heater inside the device runs with constant voltage of 110 V and a constant 0.1A of current for one hour
Describe how three-position control might be used to cause a windmill to always face into the wind. The windmill is rotated with a bidirectional DC motor.
Which of the following provides the basic attributes and behaviors of a Java window - a title bar at the top of the window and buttons to minimize, maximize, and close the window JLabel JFrame JSwing
Sketch the baseband signals for the two users when user 1 sends the bits 011, and user 2 sends the bits 101. Add the signals for the first bit only, and show that the output of the correlator for user 1 is -4, corresponding to a 0
The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 170-F capacitor is initially charged to 100 V
A 150 MVA, 24 kV, 125% three-phase synchronous generator supplies a large network. The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage.
Suppose that two optical guides embedded in a substrate such as LiNbO3 are coupled as in the below figure and the transmission length Lo=10mm. If the coupling separation d is =10µm, n = 2.2, the operating wavelength is 1.3µm
Calculate the parameters RE and XE, and the maximum efficiency and power output for the transformer when a load with a 90% lagging power factor is connected to the transformer secondary winding.
If passwords are three uppercase alphabetic characters long, how much time would it take to determine a particular password, assuming that testing an individual password requires 5 seconds
In the difference equation below K is a real number greater than 0. y[n) = x[n] + Ky[n] A) (2pt)Find the range of values of K that makes the impulse response grow without bound. B)
A negative feedback amplifier has a close-loop gain Af=100 and an open-loop gain A=105. What is the feedback factor If a manufacturing error results in a reduction of A to 103, what close-loop gain results
