Design an open-circuited, shunt stub matching network to match a 125 + j20 ohm load to a 700 MHz, 50 ohm generator. Show the lengths of your transmission lines in fractions of a wavelength. Show steps to solution please.
An alarm is powered by 120 VAC, and the on/off state of the alarm is controlled by an EM relay. Design the interface between a computer output port and the EM relay. The dropout voltage is 3.5 V, and the coil current needs
A synchronous motor has a per-phase voltage of 220V and a synchronous reactance of 10. (a) If it draws a total input power of 7.5kW at a torque angle of 30 deg, calculate the per-phase induced voltage, input current and power factor.
Design a low pass active filter such that its roll off attenuates frequency components a 10kHz or more by more than 30 db. This means that the magnitude of the transfer function (in db) at frequency 10kHz should be -30db or less
An electric motor is monitored with an ammeter, voltmeter, and wattmeter, which indicate 5.2A, 120V, and 480W respectively. Assume 60Hz. A) Draw the phasor diagram of the voltage and current,assuming the voltage at zero phase and lagging current.
