. The hysteresis comparator without opamp do not have the need to eliminate the uncertainty of switching even with infinitesimal oscillations with respect to the threshold value or deleted because before the test or irrelevant in the next circuit. A solution “cold” through a modest modification to the circuit it allows to include the hysteresis which in turn completely eliminates the output […]
TRIODES ELECTRONIC This article will be dedicated to another type of electron tube, 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 the flow of water. CONSTITUTION OF TRIODE The triode is so named because it comprises three electrodes: in addition to […]
. 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, how they behave and how to design something with them. In this series of […]
. 1 – RECTIFIERS half-wave In the last article has been briefly mentioned the use of the diode for rectification of alternating current; Now we take the topic to examine in detail the operation of the half-wave rectifier circuit. Let us refer again to the circuit considered in the previous lesson, whose schema is again shown in Fig. 1. Fig. 1 […]
. A close friend asks me if I can help in the creation of an automated mechanism for his plastic. Must replace the motorized part with the gear ratio of a beacon light with something without moving parts because of vibrations and noises, in the long run damage the same structure in which they are accommodated. not to Problem […]
Network Probe In electricians work everyday, electricians often use simple measuring instruments. To perform most of the work, it takes only two devices that work with the principle yes / no, which are owned by the network voltage and short circuit indicators. Traditionally, the mains voltage indicator, which allows to determine […]
. WHAT DOES For ESR ESR is defined as the equivalent series resistance of the components, in practice it is mainly addressed to electrolytic. It is essentially due to parasitic inductance and is all the more critical as the higher is the working frequency of the elements in question. In modern power supplies, now apart from small niches […]
HDMI 2.1 Times change, pure interfaces. Only ten years ago we began to appreciate the many benefits brought by the arrival of the HDMI cable, which she began to peep into our homes with the advent of the last generation consoles, let we abandon the good old VGA and DVI cables that until now we had so much […]
Guide pinout and USB-C USB Type-C characteristics is a specification for a USB connector system that is gaining popularity among smartphones and mobile devices and is capable both of which data transmission power delivery. Unlike his predecessors USB, is flippable, so no need to try three times […]
. Tight deadlines, hardly six years and the long political discussions last transition to digital, for the TV of tomorrow, which is the second generation digital terrestrial will already be available to everyone Italians July 1 of 2022. To define how the transition that will lead the new TV […]
