Astable Multivibrator Using IC 555: Fig. 2.105 shows the operation of Astable Multivibrator using 555 Timer IC. The threshold input is connected to the trigger input. Two external resistances RA, RB and a capacitor C…
Monostable Multivibrator Using IC 555: The IC 555 timer can be operated as a Monostable Multivibrator Using IC 555 by connecting an external resistor and a capacitor as shown in the Fig. 2.102. The circuit…
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…
