Operational Amplifier Basics
https://www.electronics-lab.com/article/operational-amplifier-basics/
Introduction This tutorial is an introduction to the Operational Amplifiers, also known as op-amps. The fundamental goal of op-amps is to amplify a voltage difference and it is the reason why we also describe them as differential amplifiers. Op-amps have been invented the exact same year as the transistors (1947) and they were originally designed […]
Parallel RLC Circuit Analysis
https://www.electronics-lab.com/article/parallel-rlc-circuit-analysis/
Introduction The series behavior of the three elementary components of electronics has been detailed in our previous article Series RLC Circuit Analysis. In this tutorial, another association known as the parallel RLC circuit is presented. In the first section, we present the elementary parallel RLC circuit and focus on its impedance. The second section focuses […]
Frequency Response of Amplifiers
https://www.electronics-lab.com/article/frequency-response-amplifiers/
Introduction As such for any electronic circuit, the behavior of amplifiers is affected by the frequency of the signal on their input terminal. This characteristic is known as the frequency response. Frequency response is one of the most important property of amplifiers. In the frequency range that amplifiers have been designed for, they must deliver […]
Raspberry Pi OLED Internet Bandwidth Display
https://www.electronics-lab.com/raspberry-pi-oled-internet-bandwidth-display/
by Archie500 @ instructables.com: In a very brief summary it works as follows: The Raspberry Pi uses SNMP (Simple Network Management Protocol) to get the WAN data rates from the router and then displays these graphically on the OLED screen. The Raspberry Pi was already set up as our media player and is next to the […]
