The interface between analog and digital signalprocessing paths in radio receivers and transmitters issteadily migrating toward the antenna as engineers learnto combine the unique attributes and capabilities of DSP with those of traditional communicationsystem designs to achieve systems with superior andbroadened capabilities while reducing system cost. Digital signal processing DSP techniques are rapidly being applied to many signal conditioning andsignal processing tasks traditionally performed byanalog components and subsystems in RF communicationreceivers and transmitters []. The incentive toreplace analog implementations of signal processingfunctions with DSP-based processing includes reducedcost, enhanced performance, improved reliability, easeof manufacturing and maintenance, and operatingflexibility and configurability [5]. Technologies thatfacilitate cost-effective DSP-based implementationsinclude a very large market base supportinghigh-performance programmable signal processing chips[6], field programmable gate arrays FPGA ,application-specific integrated circuits ASICs , andhigh-performance analog-to-digital and digital-to-analogconverters ADC and DAC respectively [7].

Book:Radio Transmitters and Receivers

Transmission and reception involve the components of a television system that generate, transmit, and utilize the television signal wave form as shown in the block diagram. The scene to be televised is focused by a lens on an image sensor located within the camera. This produces the picture signal, and the synchronization and blanking pulses are then added, establishing the complete composite video wave form. The composite video signal and the sound signal are then imposed on a carrier wave of a specific allocated frequency and transmitted over the air or over a cable network. That is the process in brief; the specific functions of colour television transmitters and receivers are described in more detail in this section. As is pointed out in the section Compatible colour television , the colour television signal actually consists of two components, luminance or brilliance and chrominance; and chrominance itself has two aspects, hue colour and saturation intensity of colour. The television camera does not produce these values directly; rather, it produces three picture signals that represent the amounts of the three primary colours blue, green, and red present at each point in the image pattern.

Radio Communication – Radio Transmitters and Receivers

Radio transmitters and receivers are electronic devices that manipulate electricity resulting in the transmission of useful information through the atmosphere or space. A transmitter consists of a precise oscillating circuit or oscillator that creates an AC carrier wave frequency. This is combined with amplification circuits or amplifiers. The distance a carrier wave travels is directly related to the amplification of the signal sent to the antenna. Other circuits are used in a transmitter to accept the input information signal and process it for loading onto the carrier wave.

Radio is the technology of signaling and communicating using radio waves. They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by a radio receiver connected to another antenna. Radio is very widely used in modern technology, in radio communication, radar , radio navigation , remote control , remote sensing and other applications.

The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation FM transfers the information by varying the frequency of the carrier wave according to the message signal. This transmitter accomplishes the most excellent range with less power.

In radio communications , a radio receiver , also known as a receiver , a wireless or simply a radio , is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves electromagnetic waves and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation.
