A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. This frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters ...4QD TEC: Audio signal (sinewave) generators
4QD TEC: Electronics Circuits Reference Archive 4QD TEC: Audio signal (sinewave) generators. There are dozens, probably hundreds of circuits for audio sinewave generators but certain 'old chestnuts' are still favourite and the basic circuits haven't changed significantly since they were built with valves.Hartley oscillator
The Hartley oscillator is an electronic oscillator circuit in which the oscillation frequency is determined by a tuned circuit consisting of capacitors and inductors, that is, an LC oscillator.The circuit was invented in 1915 by American engineer Ralph Hartley.The distinguishing feature of the Hartley oscillator is that the tuned circuit consists of a single capacitor in parallel with two ...Electronics Demonstrations Paul Falstad[email protected]

The human speech apprehend a small area of frequencies, that is extended from 300HZ until 3KHZ. This spectrum is also internationally recognized for the transmission of speech via telecommunications networks. This is also the mainer use of this circuit, one and it can be used in uses that we needed this concrete spectrum of frequencies, rejecting the spectrum on and under what, making ...YO3DAC Homebrew RF Circuit Design Ideas qsl.net
Homebrew RF Circuit Design Ideas "There is no such thing as a new idea. It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope.descrete audio amp, function generator, AC line current ...
3 Transistor Audio Amp (50 milliwatt) Here is a little audio amplifier similar to what you might find in a small transistor radio. The input stage is biased so that the supply voltage is divided equally across the two complimentary output transistors which are slightly biased in conduction by the diodes between the bases.A twin tube Geiger counter giangrandi.ch
The high voltage generator. In order to power the Geiger tube, a high voltage is required. For the SBM 20 tubes we need 400 V. Others tubes usually require between 350 and 500 V. Designing a step up converter that is simple, reliable, cheap and stable is by far the most difficult task.101 200Transistor Circuits | pooja aggarwal Academia.edu
