The basic LC Oscillator tank circuit that we discussed in one of our earlier posts has a significant limitation: it cannot alter the magnitude of its output oscillations. This means that the oscillations might be either too large or too little, making it difficult to get the desired results. It might also be difficult for […]
LC Oscillator Circuits: Explained with Calculations
An LC oscillator is a circuit which we can use to transform a direct current (DC) supply voltage into an alternating current (AC) output waveform. This output can exhibit various types of waveform shapes and frequencies which might range from complex forms to simple pure sine waves depending on the specific application requirements. These oscillators […]
Pull-up Resistors and Pull-down Resistors: How to Calculate
In my practical works, when connecting digital logic gates to external circuits or devices, I personally ensure that their inputs and outputs are properly set to provide the correct switching conditions. This is where Pull-up Resistors come into play, because they help make sure that the inputs or outputs are functioning as per the expectations. […]
Digital Buffers: A Comprehensive Overview
A digital buffer works in the same way like the NOT gate but with a distinct function. Although we find that a NOT gate (or inverter) generates an output which is just the inverse of its input, meaning that if we supply the input with a “HIGH” logic, then its output turns logic “LOW,” and […]
A Detailed Tutorial on Exclusive-NOR Gate
An “Exclusive-NOR Gate” will work by combining the functionality of an Exclusive-OR (XOR) gate and a NOT gate, but you will find that its truth table looks similar to that of a standard NOR gate, because, as we see that its output is typically at logic level “1” and switches to logic level “0” whenever […]
Understanding Exclusive-OR Gate: Tutorial
The Exclusive OR (XOR) Gate is a specialized type of digital logic gate that are widely utilized in digital arithmetic operations. Using these gates it becomes possible for us to calculate the sum of two binary numbers and we can also use these gates in error-detection and correction systems. So far in our logic gate […]
