Primes¶
- Rate Coding
- In electronics, pulse-frequency and pulse-density modulation encode an analog value as the rate of identical pulses, the basis of class-D amplifiers and sigma-delta converters.
This sourceAuthoritative reference: pulse-density / pulse-frequency modulation carries the analog value in the rate of identical one-bit pulses, decoded by a decimation filter, with oversampling improving resolution (~1/√N) at the cost of latency and immunity to amplitude noise — the basis of class-D amplifiers and sigma-delta converters.
Supported in partVerified against the publisher's abstract
This is the standard reference on delta-sigma converters, so it backs the delta-sigma half of the claim, but the only text held is a chapter listing that states no modulation mechanism.

Mechanisms¶
- Pulse-Density Modulation
- Its failure mode is that a constant or slowly varying input can drive the modulator into periodic patterns — idle tones or limit cycles — that appear as spurious tones in the recovered signal, artifacts of the deterministic loop rather than the source.
This sourceShows that constant rational inputs can generate periodic idle tones or limit cycles whose spectral lines enter the recovered signal as consequences of the modulator’s dynamics.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
