Choose the best answer for what a DC blocking or coupling capacitor does, assume the capacitor value is chosen to be too small.
Blocks the DC and is relatively high impedance to the AC voltage. Blocks only the AC voltage going into the next stage Blocks the DC voltage going into the next stage, but lets the AC signal go through Has a variable voltage gain and blocks the DC level Works well with a BJT transistor only
What are advantages and disadvantages of using digital circuits in lieu of analog circuits to measure different parameters in mechanical systems
Two identical CS amplifiers are connected is cascade. First stage is fed with a source Vsig having a resistance Rsig = 100k Ohm. A load resistance Rl = 10k Ohm is connected to the drain of the second stage.
Consider a long wire represented as distributed RC sections. The total wire length is 5mm. To reduce the wire delay, we uniformly insert n buffers along the wire. Suppose r=12Ohms/m and c=0.2fF/m and the delay of each buffer is 1ns.
A single phase 220V system draws a current of 15A at a lagging power factor of 0.8. Calculate the value of a capacitor that can be used to improve the power factor of this system to 0.95 lagging.
Determine whether the following signals are energy or power signals and compute the energy or the power a) (-1)n u (n) b) cos (πn/3 + π/6 )
120V, 60 Hz source is connected to a distribution line whose resistance, and inductive reactance is 0.001Ohm, j0.002 Ohm, respectively. Single phase, 10HP, 120V, 0.85 pf. motor and 4Kw, 120V heater are connected in parallel.
A control system for positioning the head of a floppy disk drive has the closed-loop transfer function T(s)=11.1(s+18) / (s+20)(s^2+4s+10). Plot the poles and zeros of this system and discuss the dominance of the complex poles.
The lattice constant of GaAs is a =5.65 angstrom. (a) Determine the number Ga atoms and As atoms per cubic centimeter.
A piston cylinder assembly contains 1 kg of nitrogen gas. The gas expands from an initial state where T1 = 700 K and P1 = 5 bar to a final state where P2 = 2 bar. During the process the pressure and the specific volume are related by Pv1.3 = const..
Create a state diagram for an FSM describing this sequencing behavior, having aninput bit B, and two output bits s1 and s0. Be sure to onlysequence forward by one item each time the button is pressed,regardless of how long the button is pressed-in..
the ends of a length of wire are labeleda and b. if the current in the wire is iab -3a are electrons moving toward
Design a combinational circuit that can detect whether a pattern of at least three adjacent 1s occur anywhere in an 8-bit input, and that outputs a 1 in that case. The inputs are a , b, c, d, e, f, g, and h, and the output is y.
