To save costs and reduce the large number of types of sine-wave oscillators used for various applications up to now for the generation of undamped electric oscillations, the new oscillator described here (see basic diagram, version 1 and 2) can be successfully used. This is distinguished by its simple circuit structure, its good oscillation and tuning properties and its stable oscillation behaviour compared with known oscillators. By a slight modification to this circuit (connection S of the positive-feedback resistor RM taken direct to zero potential and capacitive input coupling of the signal to the non-inverting operational amplifier input E) this oscillator can be converted to function as a selective amplifier. <IMAGE> |
