Hacks of Electronics
Understanding the common electrical sensors in healthcare and other medical devices is the first step toward appreciating the role electronics play in healthcare. This article explains the types, working principles, and applications of common electrical sensors used in healthcare in a detailed and easy-to-understand manner. Walk into any hospital today, and you will hear the […]
The Unijunction Transistor (UJT) is a three-terminal semiconductor device that is mainly used for triggering, pulse generation, relaxation oscillators, and phase control circuits. Unlike the Bipolar Junction Transistor (BJT) or Field Effect Transistor (FET), the UJT does not function as an amplifier; instead, it acts as a switching device with negative resistance characteristics. The UJT […]
Modern factories depend on interconnected systems that manage production, logistics, and quality control. As digital transformation reshapes industrial environments, network safety becomes one of the most critical factors in ensuring smooth operations. Cyber threats and system vulnerabilities pose significant risks to both productivity and worker safety, as well as regulatory compliance. Industrial firewalls play a […]
The LA3600 Audio Equalizer Circuit is a five-band graphic equalizer, meaning it divides the audio spectrum into five different frequency bands (from low bass to high treble) and allows independent control of each band. This provides a balanced and customizable audio experience. In audio systems, equalization is one of the most essential processes for improving […]
Modern electronic systems rely heavily on both digital and analog signals. While microcontrollers, computers, and digital processors handle data in binary (digital form), most real-world signals such as sound, temperature, pressure, and voltage are analog. To bridge this gap, Digital to Analog Converters (DACs) are used. A DAC takes digital input (binary numbers) and converts […]
In today’s world, most electronic devices operate digitally, but the signals we experience in the real world—such as sound, light, temperature, and pressure—are analog in nature. To process these signals in microcontrollers, digital signal processors (DSPs), or computers, we need to convert analog signals into digital form. This is where an Analog-to-Digital Converter (ADC) comes […]
