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
Ask The goal of this project is to model a system and to design a controller for the system so that the closed-loop system performs satisfactorily. We want to accurately positio
Find a minimum two level, multiple-output AND-OR gate circuit to realize these functions (eight gates minimum). F 1 (a,b,c,d) =Σm(10,11,12,15) +D (4,8,14) F 2 (a,b,c,d) =Σm(4
Q. Data transmission in Bus Topology ? Bus Topology:This topology shares a single path or link way among all users. This common single path way is called bus. In this topology,
