Experimental Class D audio amplifier

. I made a class D audio amplifier entirely with discrete components, although not the most recommended, the idea of ​​this project is purely educational to understand the operation of a class D amplifier ...

48Vdc Phantom power supply starting from 12Vac

. Hello everyone. Here is the wiring diagram, the file for the LT Spice simulator and the photos of a power supply suitable for condenser microphones and DI boxes (Direct Iniection box), all used in the music field. The cicuito ...

Variable frequency audio generator

. This circuit was created to be used to test amplification stages. It produces both square and triangular wave outputs that rise from approx 80 a 730 Hertz in a repeated cycle of approx 6 seconds. Appropriate value substitutions…

non-invasive test for injectors

. Now all engines have injectors for fuel, they are managed electronically by a control unit, which decides the injection time or the time for which the injector must remain open and therefore the amount ...

Comparator with hysteresis

. In hysteresis comparator without opamp you do not have the need to eliminate the uncertainty of switching even with infinitesimal oscillations with respect to the value of the threshold or deleted because before the test or irrelevant in the next circuit. ...

TRIODES ELECTRONIC

TRIODI ELETTRONICI Questo articolo sarà dedicato ad un altro tipo di tubo elettronico, the TRIODE, that can be compared to a faucet, since it allows to vary the current flowing through it, precisely like a tap makes it possible to adjust ...

PIPES TO ISSUE TERMOELETTRONICA

. Among the HI FI enthusiasts for several years we are always spoken of in valves amplification as the final solution for every domestic installation and not. Never having spoken here I will try to fill this gap by explaining what are the valves,…

valve Diodes

. 1 - RADDRIZZATORI A SEMIONDA Nello scorso articolo si è accennato brevemente all'impiego del diodo per il raddrizzamento della corrente alternata; Now we take the topic to examine in detail the operation of the circuit ...

Understanding of the virtual short circuit in the circuits of the operational amplifiers

.   This article explains and discusses an important simplification technique used in the analysis of the operational amplifier. A more thorough understanding of the functionality of the amplifier is, in my opinion, once…
