Electronic circuit having a linearised and symmetrized response, an oscillator having such a circuit, and a telecontrol transmitter having such an oscillator

摘要

An electronic circuit, more particularly an harmonic oscillator, is for example arranged as a transmitter for telecontrol signals, especially a remote transmitter for controlling devices such as door locks, anti-theft devices etc. in a motor vehicle. The circuit includes a device for linearising and symmetrizing the response of the amplifier of the harmonic oscillator, which is connected to the output of a means for generating telecontrol words, so as to reduce the output of harmonics.
