For the meter movement described in question 19 above, show how it may be adapted to serve as a voltmeter, with voltage ranges of 3 V and 10 V. Calculate the values for, and name, any additional components required to achieve this. Sketch the relevant circuit diagram.
If the design frequency is 4 GHz, sketch the layout of a microstrip circuit, including dimensions, to implement this matching transformer. Assume the substrate is 0.159 cm thick, with a relative permittivity of 2.2.
b. If the opamp is configured as a non inverting amplifier with voltage gain of 100, what bandwidth will the circuit have c. With the same configuration (gain of 100), what is the maximum input for linear operation (limited by VCC)
Find the frequency and period of sine waves having an angular velocity of 754 rad/s, 8.4 rad/s, 6000 rad/s and 1/16 rad/s.
Common radio uses two modulation schemes - they are AM and FM.Explain very briefly what the FM scheme is. How does itdiffer from AM What are the advantages of each scheme
A double-A (AA) rechargeable battery is rated at 1.2V, 2100mA-h ( mili-amp hours) 1- how many coulombs of charge can this battery hold 2- how many joules of energy are stored in the battery
The main mission of this project is to design and build a tap changer which is going to be fitted to power transformers for regulation of the output voltage to required levels for the Micro Grid. The tap changer system will consist of 9 changers with..
Pulse width modulation (PWM) is used to control dc voltage to an electric heater. The supply voltage is 12 Vdc, and the heating element is modeled as a 1 resistance. (a) Calculate the average power delivered to the heater when the voltage is switche..
Obtain the power factor of a two-branch parallel circuit whre th efirst branch has Z1 = 2 + j4 ohms and the second Z2 = 6 + j0 ohms. To what value must the 6-ohm resistor be changed to result in the overall power factor of 0.90 lagging
Discuss the operation of a JFET, including the pinch off and gate-source cutoff voltage in your explanation. Discuss how you can tell whether an FET is operating in the ohmic region or the active region.
Which of the following metals is the most susceptible to corrosion: cadmium, nickel (passive), magnesium, copper, or steel?
Compare the correct value of the radiation resistance of the half-wave dipole with the incorrect value that would result from using the expression for the radiation resistance of the Hertzian dipole.
