Digital Communication Techniques A video signal contains light variations that change at a frequency as high as 3.5 MHz. What is the minimum sampling frequency for A/D conversion?
There are three 2k resistors, three 1k resistors and 2 three kresistors available. design a resistor network that has an input resistance of between 3.1 and 3.4k. Minimum number of resistorsused is a prime consideration.
If the SNR must be greater than 40 dBm, how far backed-off must the amplifier operate. Assume noise comes from a third-order intermodulation between two interferers with the same power level as the wanted signal.
Shortest distance between two points. LetP1=(x1,y1) andP2=(x2,y2) be two given points.Find the third point P3(x3,y3)such that d1=d2 is minimized, whered1 is the distance from P3 to P1and d2 is the distance from P3 toP2.
A solar heating system can recharge (store heat) in a single sunny day enough to provide for the next two days. In otherwords, the only times that the solar heat must be augmented by someother heat source is when there are three of more consecutiv..
A first order allpass filter impulse is given by h(t)=-δ(t)+2e-tu(t) (a) Find the zero-state response of this filter for the input etu(t). (b) Sketch the input and the corresponding zero-state response.
An infinitely long coaxial capacitor with inner conductor radius aand outer radius b has voltage V0 on the inner conductorand V = 0 on the outer conductor. Find the electric field inthe region between the two conductors.
A power amplifier has a gain of 20 dB and an input level of 2 volts. Assuming that the input and output impedances are the same, what is the voltage level at the amplifier output
The car lead-acid battery has generally 12 V output voltage, and its internal resistance is so small that can be neglected. When starting the engine, the current of 462 A is flowing from the battery to supply the "car starter"
1) Determine the transfer of second-order highpass filter with a cutoff frequency of 900 Hz and passband gain of 1 using a butterworth type. 2) Design a filter for your transfer function using the sallen-Key topology.Find all the values of the circ..
Two infinitely long coaxial cylinders ofradii a and b ( a > b) carry surface charge+ λ and -λ respectively. Find the E field in theregion inside the inner cylinder, between the cylinders, andoutside the cylinders.
