Calculate the carrier frequency and corresponding frequency bandwidth for a microwave communication system operating at 10 cm with a microwave bandwidth of 0.2 mm and for an optical communication system operating at 1.35 micrometers with an optical bandwidth of 3 nm. What is the photon energy in Joules and in e.V. for each case? Please show all steps.
A permanent magnet DC motor has an armature circuit resistanceof Ra = 0.4Ω, a motorconstant KE = KT = 0.5 in MKS units, a motor intertiaof JM = 0.02Kgm2, and a maximum armaturecurrent Iamax = 20A.
Calculate the maximum value of Rn if the resolution of the ADC is not to be adversely affected by thermal noise. Assume the ADC operates at 25°C.
Calculate the probability that the system will fail in 3,000 hours. Supposing no failure of any component occurs in 5,000 hours of operation. What would be your revised estimate of failure rates of the components in your system?
What is the propagation constant at 500 MHz. Use the fact that the velocity of an EM wave in a lossless air-filled line is the same as that of free-space propagation in air. That is, the propagation constant is the same.
Assume that one of the pumps uses a1/4hp DC shunt motor with an input voltage of 115VDC that pulls 1.6A running at 1500 rpm. The filed resistance for the motor is 600 ohms and the armature resistance is 8.5 ohms. Find the constant KT for the motor..
The sinusoidal flux in the core of a transformer is given by φ = 0.002 Sin 377t Wb. This flux links a primary winding of 100 turns. Determine the induced voltage in the coil as a function of time.
Design the circuit so that the voltage at the gate is -12V, the drain current ID is 1 mA, and the drain to source voltage VDS is 4.7V. The JFET must be operating in the saturation region. Use standard 5% tolerance resistors.
