Simple Transistor Oscillator. This type of circuit is called a multivibrator. You can make a simple oscillator with an inductor a coil and a capacitor two parallel plates.
Output transformer 2 69 at radio shack. We have used a npn type transistor which conducts the current or get forward biased only when a positive signal is provided to its base pin otherwise it remains open or reverse biased. Jfets are three terminal semiconductor devices that can be used as electronically controlled switches or resistors or to build amplifiers.
Unfortunately its output waveform is very distorted neither sine wave nor square.
It is a simple free running oscillator circuit timed by the sizes of the resistors capacitors and power supply voltage. Crystal oscillators are used in many areas of electronics. Using a crystal oscillator circuit enables a high performance high stability oscillator to be built very cheaply and easily. The junction gate field effect transistor jfet is one of the simplest types of field effect transistor.
