Transmission of pulse length modulation information

摘要

The invention refers to switching a physical quantity, wherein the switching is performed by a switching element (SW) according to a control signal received from a control circuit (11), comprising detecting from the control signal (CS) a first number indicative of a time length, and a second number indicative of a point in time, generating a switching signal (S) comprising a switching pulse having a pulse length according to the time length and a pulse position according to the point in time, and providing the switching signal to the switching element (SW). The invention further refers to a power amplifier and to a corresponding computer program.

主权项

1. A method for switching of a physical quantity, wherein the switching is performed by a switching element according to a control signal received from a control circuit, the method comprising:
detecting, from the control signal, a first number indicative of a time length, and a second number indicative of a point in time; generating a switching signal comprising a switching pulse having a pulse length according to the first number and a pulse position according to the second number; providing the switching signal to the switching element. wherein the generating the switching signal comprises:
generating a bit sequence based on the first number and the second number;providing the bit sequence to a signal driver for transforming the bit sequence into the switching signal by:
obtaining a selected bit sequence by selecting one out of a plurality of stored sequences based on the first number;circular shifting to the selected bit sequence, or a sequence derived from the selected bit sequence, based on the second number.
