I. The passband edge frequencies of a BANDPASS BUTTERWORTH analog filter are 1200 Hz and 1400 Hz, whereas the stop band edge frequencies are 600 Hz and 2000 Hz. The stop band attenuation is 14dB. a) Find the order of the filter b) Choose a prototype low pass filter. c) Infer the transfer function H(s) of the bandpass filter d) Realize the filter using Sallen-Key structure.
A semiconductor device requires n-type material; it is to beoperated at 400K. Would Si doped with 1015atoms/cm3 of arsenic be useful in this application Could Ge doped with 1015cm-3 antimony beused
Evaluate the following convolutions using the graphical approach: h1[n]=2u[n+1]-2u[n] h2(t)=2u(t+1)-2u(n) y1[n]={2u[n+1]-4u[n]}*h1[n] y2(t)={r(t-2)-2r(t-4)+r(t-6)}*h2(t) Evaluate the step response of h1[n] and h2(t)
1. Find the volume of a cylinder whose base is 9 inches in diameter and whose altitude is 12 inches. 2. Find the following values a. cos 77 degree 3'30" b. sin 18 degree 40' 3. In a right triangle ABC, if the leg a=8 and the leg b=5. what is the angl..
The power consumption of a single-phase electric load fed froma 120V source is represented by: P(t)=100 (1-e-t/10)KW where t is the unit of time inhours. compute the energy consumed by the load over the period of 24 hours.
where the assigned loop current leaves the voltage source. If current leaves the voltage source at its positive terminal, the voltage would be positive and if it leaves the voltage source at its negative terminal,the voltage would be negative.
create a 512-length signal by using the rand command, then low-pass filter the signal with the filter h=1/2[1 1] to bandlimit the function, which can be represented with by the command filter.m with b1=b2=1/2, and a1=1
Suppose atT0 an 8-bit serial in / parallel out right shiftregister is set to value 11011010, and we want to shift in the data11101101. Show the contents of the register for each clock pulse upto next five clock pulses.
A power factor correction capacitor bank, with negligible resistance, draws a current of 625 amperes whenconnected to its 480 VAC, 60 Hz source. Calculate the capacitive reactive power of the capacitor bank.
Use the fourh order trial solution of Wx=C0+C1x+C2x2+C3x3+.....to calculate the large deflection behaviour of an initially unstressed doubly clamped beam with a point load at its center.
The column line parasitics are 1 Ohm/bit and 12 fF/bit. Determine the minimum number of repeaters which must be inserted into the row lines such that the overall access line will be reduced to less than 0.2ns.Consider a DRAM with 2^X bits. Rw = 65 ..
If we know only the following about a negative feedback system: Gain 12dB, phase 180° at 1rad/sec and gain 0dB, phase 159° at 0.2rad/sec. Determine if system is stable or not.
An npn BJT has an emitter area of 2micrometer^2. The doping concentration in the base is Nb=3x10^16/cm^3. The BJT is operating with Vt=26mV and ni=1.5x10^10/cm^3. For electrons diffusing thru the base Dn=34cm^2/s.
