A 6th order Chebyshev low pass filter has a 0.5dB ripple in the pass-band and has a cutoff frequency of 5Khz, determine the attenuation (dB) of the signal at:
1. 4Khz2. 40Khz3. 40Mhz
After a package is ejected from the plane, how long will it take for it to reach sea level from the time it is ejected Assume that the package, like the plane, has an initial velocity of 200 mph in the horizontal direction.
Consider the signal x (t) = 10+ 20 cos (100*2 t + 4) + 10 cos (250*2 t ) A. Using Euler's relation, the signal x(t) defined by the above equation can be expressed as a sum of complex exponentials in the form X(t) = x0 + Re{k=1N Xkejk2fot}
Suppose station A and B are interconnected through two parallel unreliable links, where each link has a failure probability of 0.1. Calculate the average seconds per day when A and B lose communication.
Approximately how many harmonics terms are required in the Fourier Series of a bipolar square wave with 50% duty cycle and amplitude A to represent 99% of its power?
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
Radio Systems, In design of radio systems that incorporate wireless networks, considerations must be taken such as user access, transmission direction, switching and signal strength.
Design a class - A transformer-coupled emitter-follower amplifier to deliver 10 W to an 8 Ohm speaker. The ambient temp is 25 C and the maximum junction temp is Tj max = 150 C. assume the thermal resistance value are dev-case = 3.2 C/W
Suppose a turbine is used for generating electricity, estimate the ratio of powers generated by the same speed water and air. (Water density=1g/cm3, air density =1.2kg/m3)
Draw a strain gauge circuit and its external components to attach to a conveyor mounted only at the ends to measure the load at the center of the conveyor. What type of testing would you need to do to establish a baseline and calibration curve for..
a certain ideal voltage generator is characterized as v(t) = 40 sin 377 t . If this generator is measured with a DC voltmeter, the instrument reads 12 volts, what is the rms value of this voltage waveform
Write a MATLAB script to implement the linear congruential algorithm to generate 5000 pseudo-random variates in the interval (0,1). Use the following parameters: seed=17; A=1103515245; M=2147483648; C=12345.
a. A point is equally likely to fall anywhere on the semi-circle defined by the equations, x^2+y^2=1, y>=0. Find the pdf of the y-component of the point's position. b. A point is equally likely to be found anywhere on the surface
