Patent GB-2231186-A (GB)
Title: Normaliser circuit
Inventor: HAWKES HENRY WILLIAM
IPC: H03F1/32
Filed: 1990-03-08
Abstract: A normaliser removes an unwanted amplitude-modulation and is capable inter alia of handling higher-frequency modulations than analogue dividers previously used. An input detector feeds both a long time-constant integrator 2 and a short time-constant integrator 3 whose outputs are subtracted in a circuit 4. the output of which is inverted in a circuit 5 and fed to a network of interconnected multipliers 6/1, 6/2 etc which generate successive powers of the negative signal from circuit 5. These powers are added in parallel at 8 to the output of integrator 2 and the sum fed to a multiplier 9 where it is multiplied with the normaliser input. The unwanted modulation is thereby substantially removed from the multiplier output, although circuits for removing any residuum are also described. Wanted modulations are preserved either by connecting a filter 30 to precede the network and allow only the unwanted modulation to pass, or by feeding to the network. Instead of the output of subtractor 4, the output of a detector 31 which receives a separate sample of the input signal lacking the wanted modulation. <IMAGE>
