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
Thermal noise This is the most significant noise in an ampli?er. It is produced by random movements of electrons in the resistors. This is caused by the ?uctuations in the volt
Design 8:1 Mux for a given function, f=Σ (0, 1,5,7,9, 13)
Four voicemessages, each with 3-kHz bandwidth, are to be sampled at Nyquist rate, and time- multiplexed with samples taken at twice the Nyquist rate from six analog monitoring sign
What do you understand by ASSUME assembler directive? ASSUME: This directive will be utilized to map the segment register names along with memory addresses. The Synta
Find the minimum rate of sampling that must be used to convert the message into digital form: (a) If an audio message has a spectral extent of 3 kHz. (b) If a television sign
A feedback control system with the configuration of Figure has the following parameters: K p = 0.5 V/rad, K a = 100 V/V, K m = 2.7 × 10 -4 N·m/V, J = 1.5 × 10 -5 kg·m 2 , and
Octal Number Systems Now the question may arise in one mind that why to learn octal number system when neither human nor the digital systems uses. It hence it is
Referring to Figure, let boxes 2, 3, and 5 consist of a 0.2-H inductor, a 5- resistor, and a 0.1-F capacitor, respectively. Given A = 5, and v 1 = 10 sin 10t, i 2 = 5 sin 10t ,
Explain the different types of multivibrators ? Multivibrator is basically a two-stage amplifier with output of one supplied back to the input of the other . Multivibr
