Most current video systems were defined to use negative modulation since this system has a far greater immunity to noise.

Some of the earliest electronic television systems such as the British 405-line (system A) used positive modulation.

In physical system, we can find out the useful physical information of it using small modulation to probe.

Each media has one or more different settings, which use different modulation and encoding schemes.

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

Some signaling schemes use modulation of a carrier signal (with or without wires).

Another method of conveying an analog signal is to use modulation.

The development section follows, using modulation, sequences and imitation, and including the bridge.

Some systems then use modulation to multiplex many baseband signals into a broadband signal.

Audio is encoded using 14 bit pulse-code modulation at a sampling rate of 32 kHz.
