Schmitt Trigger

Implementing Schmitt Triggers using Op-Amp One of the main applications for Schmitt triggers is interfacing signals between Analog electronics and Digital electronics, and translating levels within different logic families. One major problem encountered during this process is the pickup of noise. Digital signals are inherently fast because they deal with high frequencies and fast-… |

Design and Build a Simple Bistable Multivibrator Circuit Using Op-amp The bistable multivibrator is one of those basic circuits which you might have learnt about in your high school or college, and you probably have built one with 555 timers or with discrete components like OP-amp, transistors, or resistors. These circuits are often viewed as simple educational circuits, but not so surprising they are also used in practical designs… |

Astable Multivibrator Circuit Using Op-amp The multivibrator circuit is very popular and useful in the field of electronics, and it’s the most basic circuit that you will know about while learning basic electronics. The multivibrator circuit can be divided into two categories: the first one is known as the monostable multivibrator, and the second one is known as the astable multivibrator. But in this project, we will… |

Frequency Counter using Arduino Almost every electronic hobbyist must have faced a scenario where he or she must measure the frequency of a signal generated by a clock or a counter, or a timer. We can use an oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency, but all these devices are costly and are not for everyone. With that in… |

Capacitance Meter using Arduino When we come across circuit boards which are previously designed or we take out one from old TV or computer, in attempt to repair it. And sometimes we need to know the capacitance of particular capacitor in the board to eliminate the fault. Then we face a problem in getting the exact value of capacitor from the board especially if it is a Surface Mount Device. We can buy… |

Schmitt Trigger Gate Schmitt Trigger gate is a digital logic gate, designed for arithmetic and logical operations. It provides OUTPUT based on INPUT voltage level. A Schmitt Trigger has a THERSHOLD voltage level, when the INPUT signal applied to the gate has a voltage level higher than the THRESHOLD of the logic gate, OUTPUT goes HIGH. If the INPUT signal level is lower than THRESHOLD, the… |
