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
A conical tank is shown in Figure. The tank is filled with water. Using MATLAB, determine: a. the volume of water in the tank b. the weight of the water in the tank.
Need a phd expert in optical system and networking
The various flags are: - Sign flag, Axillary flag, Zero flag, Parity flag, Carry flag.
We shall demonstrate load-line analysis to find the diode current and voltage, and then compute the total power output of the battery source in the circuit of Figure (a), given the
Q. Explain the high-frequency response of FET amplifier? The analysis for the high frequency response of the FET amplifier is almost the same as that of the BJT amplifier. The
Q. Determine the transfer function C(s)/R(s) of the nested-loop feedback system shown in Figure.
