A Hi-Fi surround sound system (5.1) typically consists of 4 speakers at the corners of the room, and a center speaker just below or above the TV or the video system. This center speaker becomes the main speaker box of the surround sound since it is responsible for delivering the high quality voice output from […]

Solar Charge Controller for 100 Ah Battery
This comprehensive solar charge controller is designed to effectively charge a big 12 V 100 Ah battery with utmost efficiency. The solar charger is practically foolproof in terms of battery over charge, load short circuit, or over current conditions. By Vismit Singh The key elements of this 100 Ah solar regulator circuit are, obviously the […]
Sine-Cosine Waveform Generator Circuit
The circuit discussed below is designed to generate precision sine and cosine waveforms, which are perfectly identical with their dimensions, but are 90° out of phase. There are a variety of applications which often demand a couple of sinewave frequencies which are of the identical frequency, but 90° out of phase. Simply put, a sine […]
Simple Triac Phase Control Circuits Explored
In a triac phase control circuit, the triac is triggered ON only for specific portions of the AC half cycles, causing the load to operate only for that period of the AC waveform. This results in a controlled supply of power to the load. Triacs are popularly used as a solid-state replacement of relay for […]
LM10 Op Amp Application Circuits – Works with 1.1 V
The LM10 is a pioneering operational amplifier designed to operate from single ended power inputs with voltages as low as 1.1V, and up to as high as 40V. As can be witnessed in Figure 1, the device consists of an op amp, a precision 200 mV band-gap voltage reference, and a reference amplifier, all encased […]
