Electric signal conversion

摘要

In one aspect, an electrical signal converter is disclosed. The exemplary electrical signal converter may include a plurality of ordered converter elements. Element selection logic may be provided to pseudorandomly select a pointer to a switch matrix, wherein the switch matrix maps converter elements according to a stepwise “delta-two-maximum pattern.” Advantageously, pseudorandom stepwise delta-two-maximum patterns may be applied both to a first order converter, and to a feedback converter for error correction.

1. An electrical signal converter, comprising:
a plurality of inputs for receiving a first species of signal;
a plurality of n, converter elements for converting the first species of signal into a second species of signal, wherein n>3;a switch for mapping the plurality of inputs to the plurality of converter elements; andlogic configured to cause the switch to map the inputs on a plurality of successive input cycles to different converter elements according to a delta-two-maximum pattern, wherein on a first input cycle, a converter element is used at position k, and on a second conversion cycle the converter element is used at position kt+1, wherein |k−kt+1|≦2.
