Filters are not new in electronics. Depending on your needs, you are likely to come across several types when searching for a good filter design. Such an example is a passive high-pass filter. It is a popular circuit in audio processing and signal conditioning. With that in mind, what else is there about passive high-pass filters? […]

Introduction Because of their many applications, differential amplifiers remain a common circuit in electronics today. However, those who have yet to interact with such a circuit might ask, what is a differential amplifier? We can define a differential amplifier as a circuit designed to take two inputs and only amplify the difference between the two […]

There’s an unspoken rule in tech that if your device has wires, it probably runs faster than its wireless counterpart. This is true to a certain point, but if there’s a faster alternative, wouldn’t you switch over?   What is a Wireless Adapter? We’re talking, of course, about wireless adapters. They’re hardware you can attach […]

Introduction What Is a non-inverting operational amplifier? How does it work? What are its applications? These are just some of the questions people might have in mind if they are new to operational amplifiers. A non-inverting operational amplifier is a type of circuit where the output voltage is in phase with the input voltage. In this […]

Introduction A passive low pass filter is an electrical circuit that allows low-frequency signals to pass through while reducing or attenuating the high-frequency signals. It is a passive filter because it uses passive components such as capacitors, resistors, and inductors to achieve this operation. We go deeper into understanding what a passive low pass filter is […]

Current Dividers Explained! Introduction A current divider is a type of circuit where a single current input is divided among multiple branches or paths. The value of each current path depends on the resistance of each branch, which is determined by the current divider rule. Understanding the Current Divider Rule The current divider formula is essential […]
