555 Timer Circuit: The timer IC 555 Timer Circuit is most versatile linear integrated device introduced by Signetics corporation in early 1970. It is basically a monolithic timer circuit which can be used in many…
Wien Bridge Oscillator using Op Amp: This is also RC oscillator which uses RC type of feedback network. The main difference between phase shift and Wien bridge oscillator is that the R-C phase shift oscillator…
RC Phase Shift Oscillator Using Op amp: RC Phase Shift Oscillator basically consists of an amplifier and a feedback network consisting of resistors and capacitors arranged in ladder fashion. Hence such an oscillator is also…
Triangular Wave Generator Using Op amp: We have seen that, the output of integrator is a Triangular Wave Generator Using Op amp if its input is a square wave. This means that a Triangular Wave…
Square Wave Generator Using Op amp: The Square Wave Generator Using Op amp means the astable multivibrator circuit using op-amp, which generates the square wave of required frequency. The Fig. 2.83 shows the square wave…
Second Order High Pass Butterworth Filters: The second order high pass Butterworth filters produces a gain roll off at the rate of + 40 dB/decade in the stop band. This filter also can be realized…
First Order High Pass Butterworth Filter: As mentioned earlier, a high pass filter is a circuit that attenuates all the signals below a specified cut off frequency denoted as fL. Thus, a high pass filter…
Second Order Low Pass Butterworth Filter: The practical response of Second Order Low Pass Butterworth Filter must be very close to an ideal one. In case of low pass filter, it is always desirable that…
First Order Low Pass Butterworth Filter: The first order low pass butterworth filter is realized by R-C circuit used along with an op-amp, used in the noninverting configuration. The circuit diagram is shown in Fig.…
Butterworth Polynomials: The filter in which denominator polynomial of its transfer function is a Butterworth polynomial is called a Butterworth filters. The Butterworth polynomials of various orders are given in the Tables 2.3 and 2.4. The…
