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
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..
Three screws are drawn at random from a lot of 100 screws, 10 of which are defective. Find the probability that the screws drawn will be nondefective in drawing (a) with replacement, (b) without replacement.
A repeater has an input signal of 150μW and an output signal-noise ratio of 20 dB. The repeater has a gain of A and additional noise of N. What relation should the two parameters satisfy to maintain an output noise figure less than 2 dB
The voltage across the terminals of a certain circuit and the current entering into its (+) voltage terminal are given by: v = 4 + 12 Cos[377 t + 60 Degree] - 6 Cos[754 t - 30 Degree] i = 5 + 10 Cos[377 t + 45 Degree] + 2 Cos[754 t + 15 Degree] What ..
The source has an abc-phase sequence. At the wye-connected load, the phase-a voltage Va'n' has phase angle (theta)a'n' = 60 degrees and the phase impedance is (10 + j15) ohms. Further, the line impedance per phase is (1.1+ j1.5) ohms
When a square wave with a fundamental frequency of 2khz and amplitude 5v and comprised of up to five odd harmonic (each successive odd harmonic having half the amplitude of its predecessor) is passed though a standard telephone line of bandwidth o..
You have a 10 nH inductor. What value of capacitor should you put in series with the inductor to achieve an impedance of Z=j50 ohm at f=1.0 GHz
A transmission line is specified by the following, while operated at omega w=6*10^8 rad/s, L'= 0.4*10^-6 H/m, C'=40*10^-12 F/m, G'=80*10^-6 S/m, and R'=20 ohms/m. Find the attenuation rate after a wave propagates 10 meters on this line.
An early code used in radio transmission involved using codewords that consist of binary bits and contain the same number of 1s. Thus, the 2-out-of-5 code only transmits blocks of 5 bits in which 2 bits are 1 and the others 0.
A polar binary pulse are required with peak amplitude Ap= 1mV, the channel noise is rms 192.3 μV theshold detection not used. 1 & 0 are equally likely. Find the detection error probability. Also find the error probability for a)ON, OF.
What would be the minimum sample rate needed to adequately acquire an EKG signal Note that this problem is not as simple as it appears to be, because while the fundamental frequency may be relatively low, artifacts in the EKG may be at frequencies..
Draw the correct circuit to serve a 7.2kv single-phase load from a 2.4kv source. If the laod is 50kVa at pf=.8 lagging, compute the secondary and primary phasor currents. is this a step-up or step-down application
