Our assembly is a very useful test device, especially for readers who work setting up and repairing audio devices. It is an audio generator which produces three waveforms: rectangular, triangular and sinusoidal, a true generator of functions capable of covering the range that goes from 20 Hz to 200 000 Hz.
This is a different signal injector, as it does not need to connect to the analyzed circuit. What it does is to inject a signal into components that have coils and that is why they can pick up signals through a magnetic field. Simple to assemble, it can be very useful in the assembler's and electronic repairman’s workbench.
We describe the assembly of a very useful instrument for your workbench that is used to detect the presence of audio and radio frequency signals in your designs or in which you have to repair radios.
IGBTs are widely used in frequency inverters, power controllers, switched sources and DC/DC converters. These components have hybrid features, with an isolated gate as a MOSFET and junctions between the collector and emitter as a bipolar transistor.
We have dealt with in our articles on the advances of science in relation to the phenomena that occur in our body, especially in our brains, which lead to speculation about many phenomena hitherto termed "paranormal". The advances continue and now in 2018 we have a new scale of extremely promising and at the same time scary discoveries about the possibility of quantum computers in our brain and even communication with other dimensions. See more in this article.

IGBTs are hugely important components for power electronics appearing in inverters, high power load switching, motor controls and more. In this article, which is part of the contents of our book Electronics Course - Power Electronics we show how to interpret the characteristics and specifications of the IGBTs.
