A digital model of pulse-density modulation can be obtained from a digital model of the delta-sigma modulator.

Pulse-density modulation, or PDM, is a form of modulation used to represent an analog signal with digital data.

Pulse-density modulation (PDM)

In a pulse-density modulation bitstream a 1 corresponds to a pulse of positive polarity (+A) and a 0 corresponds to a pulse of negative polarity (-A).

LPCM is the method of encoding generally used for uncompressed audio, although there are other methods such as pulse-density modulation (used also on Super Audio CD).

In pulse-density modulation, a high density of 1s occurs at the peaks of the sine wave, while a low density of 1s occurs at the troughs of the sine wave.

It was in effect slow pulse-width modulation of motor power according to load.

If you slowly change the offset amount, you create pulse-width modulation.

The additional pin is used for a pulse-width modulation signal to provide variable speed control.

Any of these pins can be used for the timing or pulse-width modulation output techniques described above.

This is a kind of pulse-width modulation.

It can be seen that this looks like pulse-width modulation, but would obviously result in poor control and large variations in speed.

It has an electronic motor control board which uses pulse-width modulation, and can provide up to 55 amps when required.

In this case we will use pulse-width modulation for a dynamically changing tone:

Pulse-width modulation (PWM) is a common method of controlling computer fans.

It may also include analog-over-analog pulse modulatated baseband signals such as pulse-width modulation.

Changing the square wave as described above is an example of pulse-width modulation (PWM).

Pulse-width modulation - Another modulation scheme that produces continuous motion through discontinuous switching.

This technique is known as pulse-width modulation (PWM).

In many synthesizers, the duty cycle can be modulated (sometimes called pulse-width modulation) for a more dynamic timbre.

A servo may be controlled using pulse-width modulation (PWM).

Modern engines utilize solid-state control which allows the fuel pressure to be controlled via pulse-width modulation of the pump voltage.

One of the most common types of speed controllers uses pulse-width modulation (PWM).

The 555 can be used to generate a variable pulse-width modulation (PWM) signal using a few external components.

Advanced electronic ballasts may allow dimming via pulse-width modulation or via changing the frequency to a higher value.

- Data-logging, multiplexing and pulse-width modulation.

Four types of pulse-width modulation (PWM) are possible:

Dimming: LEDs can very easily be dimmed either by pulse-width modulation or lowering the forward current.

Nichrome heating elements were controlled by pulse-width modulation (PWM) of transistors.

They use dynamic amplitude modulation, which is generated by using pulse-width modulation, a technique also used in modern static inverters.

This method is also called pulse-width modulation (PWM) and is often controlled by a microprocessor.

Pulse-width modulation (PWM), or pulse-duration modulation (PDM) is a modulation technique that conforms the width of the pulse, formally the pulse duration, based on a modulator signal information.
