# N-M6 Oscillators Module

## INNOVATIVE SYSTEMS

With the Oscillators Module, "N-M6", designed by EDIBON, the different oscillators can be studied: RC and LC network oscillators, Wein bridge, Colpitts, Hartley and the astable multivibrator.

See general description

## General Description

Oscillators operation is usually very similar in all of them: the oscillating circuit produces an oscillation, then the amplifier increases it and finally the feedback network takes a part of the energy from the oscillating circuit and introduces it back into the input producing a positive feedback.

In short, the oscillator is an electronic stage which, being supplied with a DC voltage, produces at its output a periodic signal, which may be roughly sinusoidal, or square, or sawtooth, or triangular, etc. The essence of the oscillator is to "create" a periodic signal by itself, without any signal having to be applied to the input.

With the Oscillators Module, "N-M6", designed by EDIBON, the different oscillators can be studied: RC and LC network oscillators, Wein bridge, Colpitts, Hartley and the astable multivibrator.

In addition, faults can be simulated in most of the circuits under study. The student must investigate what is happening in the circuit and why it is not working properly. These faults simulations can be of several types from damage components to a hypothetical incorrect circuit assembly.
