Abstract
This electronic apparatus comprises a power amplifier formed by an output stage (,) that has a non-linear amplification characteristic, and a correction assembly (,) for compensating for the non-linearities of said characteristic. This assembly is formed by a low-power preamplifier (,) of the same type as said power stage, consequently presenting the same non-linearity as stage (,). The combining device (,) combining the signals applied to the input terminal (,) with the output signals of said preamplifier (,) largely counteracts the non-linearities of said characteristics.
