Abstract

The reception apparatus according to the invention comprises a receiving antenna (1), a fixed-gain preamplifying element (2), an amplifying element (8) having a series of output lines (13) with fixed amplification levels connected to a common conversion element (20) by way of a sampling element (17), the conversion element (20) being associated with a storage element (21) and with a stored signals selection means (22) for transmitting to a digital processing unit (23) those of the stored signals having the amplification level best matched to the digital processing unit (23). <IMAGE>
