| titleOfInvention | Arrangement for generating an angle-modulated carrier signal of constant amplitude in response to data signals |
| abstract | An arrangement for generating an analog anglemodu- lated carrier signal of a substantially constant amplitude in response to data signals having a sumbol rate 1fT comprises a read-only memory (21) for storing modulation parameters, an addressing circuit (22) responsive to a predetermined number of consecutive data symbols for producing read addresses with a rate q/T, where q is an integer greater than 1, and a signal processor (27) for processing read values to form the analog angle-modulated signal. An arrangement having a predominantly digital structure which does not utilize a DAC circuit as an interface between digital and analog sdections of the signal processor is obtained in that the signal processor incorporates a zero-crossing generator (41) comprising a delay circuit (42) responsive to a numerical timesetting signal a set pulse having a presettable time delay of at most T/q, a gate circuit (43) only responsive to a zero-crossing indication signal for transferring the set pulse to a bistable pulse generator (44), which produces a two-level signal whose level transitions only occur at the instants of the transferred setting pulses, and a bandpass filter (18) having a centre frequency equal to the carrier frequency. these measures result in an arrangement which is capable of processing a wide range of data symbol rates 1/T and which is particularly suitable for monolithic integration. |
