CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the priority from the Indian provisional application numbered 20181 1022779, titled“Zero Bandwidth Modulation Process” filed on 18th of June 2018.

FIELD OF THE INVENTION

The present invention relates generally to transmission of radio signals and more particularly to transmission of radio signals minimizing sidebands.

BACKGROUND OF THE INVENTION The known modulation apparatus and modulation processes are believed to contain all the information in sidebands and require finite bandwidth which is proportionate to highest signal frequency. The technique is universally applicable to amplitude modulation, frequency modulation, phase modulation, on/ off keying and many combinations of these processes. With all known modulation processes require higher modulated carrier bandwidth, in proportion to highest signal frequency and highest data rate. The RF carrier is an electromagnetic wave having characteristic that can be modified from known reference according to modulating signal. Modulator is a device where the carrier and modulating signals come together to create modulated carrier. Modulation process is known to alter characteristics of the carrier wave like amplitude, phase, frequency and other individually or in combinations. Such processes produce intermodulation products resulting as sidebands, in modulated carrier wave output, which are believed to carry all the signal information. These sidebands vary in amplitude and bandwidth depending on various factors including type of modulation, quality of signal, reliability factors and others.

Sidebands in prior art are generally on both sides of the carrier known as upper side band and Lower side band and carrying all the information. Some modulation systems transmit carrier with one sideband suppressed completely or partially to conserve bandwidth.

Modulator having more than one carrier waves are known for carrying large data and wide band signals. Modulating signal may be of digital and/or analog types such as voice, picture, text, data with wide variety of raw information, coded, multiplexed, compressed, encrypted or processed. Modulation process and devices known in prior art always have a demodulation known as demodulator. Demodulation is known as a process of deriving the original information from modulated carrier wave. Effect of demodulation apparatus and process is always exactly complimentary to the modulation process, separating the information and carrier wave, demodulators will have decoder, demultiplexer, decompressing, de-encrypting and other processes to faithfully recover information in original form.

Since the prior art modulation processes consume spectrum with bandwidth according to modulating signal, making available only finite numbers of frequencies for transmission of information using waves. This availability of limited numbers of frequencies has resulted in government regulating the resource. The regulation also ensures non-conflicting and fair use of this limited resource. Demand far outstrips the supply in numbers of modulating frequencies available for commercial and public use thus deny it to some. In view of the above facts, there is a need in the art for more efficient use of available spectrum to convey maximum information while consuming minimum bandwidth of the spectrum for each Radio Frequency modulating signal. The need for process to conserve spectrum bandwidth using a variety of modulation types in various modes of radio frequency communication system. OBJECT OF THE INVENTION

An object of the present invention is to produce pure sine wave for transmission of signals

Another object of the present invention is to reduce the bandwidth requirement in communication system. Another object of the present invention is to remove sidebands produced during modulation.
