Q. Explain Inductorless Filters
Inductorless (Active) Filters
Filters (used to pass or eliminate certain frequency components of a signal) that are suitable for IC fabrication, but which do not contain inductors, are known as active filters. They have the op amp as a common component. Figure 5.4.13 shows the basic op-amp circuit with frequency-dependent impedances. The voltage gain or voltage transfer function of this circuit is given by
with Zi = Ri and Zf = Rf (1/j ωCf ) (i.e., Rf and Cf in parallel). We have a low-pass filter with
is sketched in Figure 5.4.14, from which one can see that at the half-power or 3-dB point of fl, the dc value Rf /Ri goes down by a factor of 1/ √ 2 or 0.707. With Zf = Rf and Zi = Ri + 1/j ωCi (i.e., Ri and Ci in series), we have a high-pass filter for which we obtain
What is basic requirement of semiconductor laser? Draw its label diagram and explain its working with necessary theory. Write down the applications of semiconductor laser.
Q. Determine the open-circuit output voltage v o of the system shown in Figure as a function of the input voltage v i .
Q. Three single-phase, 10-kVA, 2400/120-V, 60- Hz transformers are connected to form a three- phase, 4160/208-V transformer bank. Each of the single-phase transformers has an equiv
Why do wenot see the battery and capacitor combination for power backup? Ans) There are "super capacitors" that are used for power backup - they are well-organized for short-te
Explain the terms: valence band, conduction band, valence electrons, and energy gap with the help of suitable diagrams. Valence Electrons: The electrons in the outermost orbi
Q. What is Digital system components? The reason that digital systems are so inexpensive and yet so powerful is that they consist of very large numbers of just a few building
Q. A50-kW, 230-Vcompound generator has the following data: armature-circuit resistance 0.05 , series-field circuit resistance 0.05 , and shunt- field circuit resistance 125 . As
This problem is with circuits. It is basic circuit problem. I need a very detailed step by step on how we arrived at the solutions. Only respond if you are 100% sure on your answer
Q. A transmission line with air dielectric is 25 m long. Find, in wavelengths, how long the line is at frequencies of 1 kHz, 10 MHz, and 100 MHz.
(a) Design a passive high pass filter that has a maximally flat response with a 50 Ω resistive load. Assume that the cut-off frequency is 40 kHz and that at a frequency of 25 kHz,
