Reflections on the mains voltage

Dopo il mio anno sabbatico dovuto a epidemia con relative complicazioni e diversi lutti ritorno a pubblicare È risaputo il fatto che se si deve andare negli Stati Uniti, After my sabbatical due to an epidemic with related complications and various griefs, I return to publishing It is well known that if you have to go to the United States

After my sabbatical due to an epidemic with related complications and various griefs, I return to publishing It is well known that if you have to go to the United States

Niente più valvole dalla Russia Lo stop all’export delle valvole dalla Russia ha messo in allarme i musicisti. After my sabbatical due to an epidemic with related complications and various griefs, I return to publishing It is well known that if you have to go to the United States

Nyquist-Shannon theorem

. Comprensione dei sistemi campionati Il teorema di campionamento di Nyquist, or more precisely the Nyquist-Shannon theorem, it is a fundamental theoretical principle that governs the design of mixed signal electronic systems. Technology…

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 ...

Simulated inductance

. I recently designed several variable power supplies to test tube amps, actually I designed more than one at the same time with different characteristics. They all have one component in common with the rotator. The shooter ...

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…

Low resistance meter

Create a circuit for the precise measurement of low resistances. You already have a DMM to measure resistance, but it can be used with resistances lower than 1Ω? And if so, these low resistive readings are reliable? This…

9V by a ni-cd battery with USB charging

. Poking even once in all the drawers looking for a 9V battery charged for a multimeter that has shut in time of need (how could it be otherwise?), I thought it would be nice to have a box of ...

The IGBT Protection

. Principio di funzionamento I primi IGBT erano tiristori modificati per potersi accendere con un comando in tensione. Consider the BJT equivalent circuit of a thyristor and a MOSFET transistor is added between the collector and emitter ...

BATTERY POWERED TESTER

. TESTER BATTERIE AUTOALIMENTATO Dietro pressanti richieste di un'amica che lavora come addetta all'accettazione presso un centro assistenza ho progettato un tester veloce per batterie. You can not imagine how many come with remote controls ...
