1. Assume 1800.0 MHZ EM wave propagates in the z- direction with E pointing in the x-direction and E0 = 20.00V/m
i Calculate the wavelength
ii. Calculate the magnetic flux density
iii. Calculate the magnetic field intensity
2. It is found that the attenuation on a 50 distortion less transmission line is 0.01dB/m. The lines has capacitance of 0.1Pf/M. Find the inductance per metre of the line.
Design a Common Emitter amplifier with no bypass capacitor to obtain a voltage gain of -10 when Rin= 2k, Rload= 4k, VCC= 15V, VBE= 0.6V, and beta= 300. This amplifier requires an output swing of 4V peak-to-peak.
the switch has been open for along time .at t0the switch is closed .find the differential equation for capacitor
Consider two signals that have the same frequency. When the amplitude of the first signal is at its maximum, the amplitude of the second signal is at half its maximum from the zero level. What is the phase shift between the two signals
given appositive number α, determine the constants A,B,C such that the iteration converges locally to 1/α with orderp= 3. (this will give a cubically convergent method for computing the reciprocal 1/α which uses on addition, subtraction, and multi..
Describe how I/O ports are accessed in system that uses Memory-Mapped I/O and how they are accessed in a system that uses Direct I/O. List the advantages and disadvantages of each type of port addressing.
Overflow occurs when a result is too large to be represented accurately given a word size. Underflow occurs when a result is too small to be represented correctly (for example, a negative result while doing unsigned arithmetic.).
When making an impedance diagram, does inductive reactance go on the positive Y-axis, or the negative Y-axis. How about capacitive reactance. How do these graphical representations relate to the phase angels of the reactances.
an electrical transformer dissipates heat equivalent of 3000 kW/h. the inlet and outlet temperatures of the cooling water are 55C and 15C respectively. calculate the mass of the cooling water in a minute.
Recall that for discrete sequences the ts sample period (the time period between samples) is the reciprocal of the sample frequency fs. Write the equations, describing time-domain sequences for unity-amplitude cosine waves
A DC series generator is supplying a current of 5A to a series lighting system through a feeder of a total resistance 10 ohms.The terminal voltage is 2500V and the armature series field resistance 18 ohms and 15 ohms respectively.
a)Describe the difference between a relay logic system and a PLC control system. Are there any advantages of PLC control system over relay system. Explain the advantages in details with one example.
