single-sideband modulation , SSM (skrót)

Steps may be taken to reduce this effect, such as single-sideband modulation.

As an alternative single-sideband modulation can be used, giving precise control over the number and amplitude of the harmonics.

In single-sideband modulation schemes, twelve voice channels would be modulated into a channel group.

This signal can be fed into an single-sideband modulation transmitter, which in part modulates the carrier wave.

During the 1950s, hams helped pioneer the use of single-sideband modulation for HF voice communication.

The dispersion penalty vanishes with single-sideband modulation.

He invented single-sideband modulation.

A weird animal quacking or an unintelligible human voice is a likely sign that the transmitter is using single-sideband modulation.

Single-sideband modulation produces a modulated output signal that has twice the bandwidth of the original baseband signal.

Completely suppressing both the carrier and one of the sidebands produces single-sideband modulation, widely used in amateur radio and other communications applications.

It could also be used to amplify the power output of a single-sideband modulation transmitter to a peak envelope power of 30 kilowatts.

Using a receiver capable of demodulating single-sideband modulation, SSTV transmissions can be heard on the following frequencies:

The Marine Radiotelephone Service or HF ship-to-shore operates on shortwave radio frequencies, using single-sideband modulation.

Single-sideband modulation (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth.

In 1927, a second transmitter was installed to initiate the first transatlantic commercial telephone service; linking New York and London on 60 kHz using single-sideband modulation.

Single-sideband modulation avoids this bandwidth doubling, and the power wasted on a carrier, at the cost of increased device complexity and more difficult tuning at the receiver.

Amplitude modulation (AM) was once the main voice mode in amateur radio before being superseded by Single-sideband modulation (SSB).

Multi-frequency versions with plug-in taps have become the mainstay for multi-band Single-sideband modulation (SSB) HF communications.

Single-sideband modulation (SSB, or SSB-AM)

Telegraphy and digital modes are the most commonly used for communications, but speech transmission via amplitude modulation (AM) or single-sideband modulation (SSB) is also allowed.

In 1915 he invented single-sideband modulation to transmit multiple telephone calls simultaneously on a single electrical circuit, and was responsible for installing the first such system between Pittsburgh and Baltimore.

In the case of single-sideband modulation (SSB), the carrier is suppressed (and in some forms of SSB, eliminated).

Early attempts were made to use radiotelephone using amplitude modulation and single-sideband modulation within the band starting from 20 kHz, but the result was unsatisfactory because the available bandwidth was insufficient to contain the sidebands.

The six-tube versions added either a RF amplifier tube, a push-pull audio power amplifier tube, or a beat frequency oscillator tube (to listen to Morse code or single-sideband modulation transmissions).

The society operates a radio shack outside Cambridge and frequently enters amateur radio contests such as CQWW in both the single-sideband modulation (SSB) and carrier wave (CW) category.
