Write a program to compute the impedance Z and the inductance L of an electrical coil, given the voltage V, current I (amps), resistance R (ohms), and frequency F (cycle/second). Make use of selection and conditional repetition.
The circuit is a close loop with current running from the Voltage source to the resistor, then the coil and back to the voltage source.Get several sets of input from the user in one line: Voltage, Current, Resistance, Frequency in one line. (4 inputs)Then output the results in sets in one line: Voltage, Current, Impedance, Reactance, Inductance in the following line. (5 inputs)
The interface must be such that the user is offered logical and clear choices of options to select from, and the program should be able to continue indefinitely as long as the use is willing to provide input.
a coaxial cable can carry signals in the range 50mhz to 450mhz. The bandwidth of cable is divided into a numbe of sub-channels each occupying with the guard band, 40mhz of bandwidth. In each channel the guard band takes up 4 mhz
design and implement an access control circuit for my research lab. There are two inputs - a key card swipe on the door that produces an ID in the 0.7 range, and a day/night sensor that is 1 during the day, and 0 at night.
A finite state machine has one input, X, and one output, Z. The output becomes 1 and remains 1 thereafter when, starting from reset, at least two 1s and one 0 have occurred as inputs, regardless of the order in which they appeared.
Suppose that a 5 Mbps link is being shared by a number of users. Each user alternates between period of activity during which the user transmits at rate 1 Mbps and periods of silence, when the user does not transmit.
The bandwidth of interest is between 0.5 and 50 Hz and has peak amplitude of approximately +/-1 mV. -a. Design and draw a block diagram (not circuit) of the signal conditioning portions (everything before ADC) of your system.
A coaxial cable connects a 50W transmitter to an antenna with a feed impedance of 200W. The operating frequency is 900MHz and the cable has a velocity factor of 0.66. Determine the characteristic impedance and length of the cable.
A meta dyne with a uniform air gap is driven at constant speed with a constant dc voltage applied to the q brushes the stator is unexcited. Determine the current in the two circuit and the voltage between the q brushes. what driving torque will be..
Write the formula for the magnetization volume current density J M and magnetization surface current density JMS in terms of magnetization vector M. 4. A sphere has permanent magnetization where is a positive constant.
Two identical CS amplifiers are connected is cascade. First stage is fed with a source Vsig having a resistance Rsig = 100k Ohm. A load resistance Rl = 10k Ohm is connected to the drain of the second stage.
Four signals, each having W = 3 kHz, are to be frequency-division multiplexed with 1-kHz guard bands between channels. The subcarrier modulation (modulation to accomplish the FDM) is AM, with one signal left at baseband.
Two transistors, fabricated with the same technology but having different junction areas, when operated at a base-emitter voltage of 0.72 V, have collector currents of 0.2 mA and 12 mA. Find Is for each device.
A shunt regulator utilizing a zener diode is biased on through a 100ohm resistor. Determine the change in the regulated output voltage for the two situations below a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constan..
