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
One byte Instructions One byte instruction include both the opcode operand in the same byte. To identify one byte instruction one must observe followings things .
Rectifiers As discussed above the purpose of the rectifier is to convert the incoming ac from a transformer or other ac source to some form of pulsating dc. That it i
i cant imagine of something called complex frequency...i find it important for laplace transformation,but i am lacking the physical explanation,please explain this to me
find the resultant of two forces 20N and25N acting at an angle 60 degree each other
If E b /N 0 = 20 in a coherent ASK system, find the value of Eb/N0 that is needed in a noncoherent ASK system to yield the same value of Pe as the coherent system.
