An ultra wideband (UWB) radio transmitter, operating from 3.1 to 10.6 GHz, drives a parallel RC load with R = 75 and C = 0.6 pF. What is the best return loss that can be obtained with an optimum matching network?
Assuming DS = 1200H, BX = 0100H, and SI = 0250H, determine the address accessed by each of the following instructions. Assume real mode operation. (a) MOV [100H], DL (b) MOV [SI+100H], EAX
A 1 F capacitor is being charged through a 100 Ohm resistor. How long will it approximately take for the capacitor to reach about 63% of its final charge.
Explain and show how ultrasonic range-finding works and is used. Include visual information wherever possible to most effectively convey the information. This section must be organized using headings and subheadings - consider the most effective l..
A Si sample is uniformly doped with phosphorus at 5 E 16 cm^-3. We make a p-n junction by implanting boron atoms into the surface layer. The implanted depth is 0.15 µm. What should the surface concentration of the boron implant
consider a coil which has a resistance of 0.314omega and an inductance of 0.002 h being supplied by 240 vrms 50 hz ac
The receiver is designed to receive transmitted signals between 5 MHz and 25 MHz. High-side tuning is to be used. Determine the tuning range and tuning ratio of the local oscillator if the IF frequency is 400 kHz and 2 MHz, respectively.
A multi-frequency signal is input to a first-order, low-pass filter. A 60 kHzcomponent is found to be reduced in amplitude by a factor of 90. Find the break frequency of this filter. determine the factor of reduction for the 5 kHzcomponent.
The ATSC broadcast television system used in the US transmits video signals at an average rate of 18.34 Mbps and employs 8-VSB modulation.
Design a low pass active filter that passes frequencies at 900 Hz and below and at these values the magnitude (in dB) of the transfer function is between 23 dB and 17 dB. The circuit's magnitude (in dB) of the transfer function at a frequency of 1..
An induction motor has an output or shaft power of 30 kW at 86% efficiency. For this operatingcondition, stator copper loss = rotor copper loss = core loss = mechanical rotational losses. Determine the slip.
Discuss the possible difficulty of such an approach.
A certain antenna has a radiation resistance of 51 ?, and an ohmic (loss) resistance of 10 ?. If a current of 2 A is driving the antenna, calculate the following: a) the power radiated. b) the power lost due to heat.
