4. Classification 1.In analog video systems: the emission transductors generates an analog electrical signal whose value varies continuous between two limits determined the minimum and maximum luminance corresponding object image captured. Processed and transmitted signal from this channel TV forms at reception, with help from signal traductors-image TV, TV image of the object Custom vintage analogue synthesiser system equipment. The Analogue Systems website contains details and instructions on the modules and complete vintage style synthesizer systems manufactured by Analogue Systems. http://www.analoguesystems.co.uk/

5. Classification 2. In analog-digital video systems: images obtained signal to electrical signal conversion is of a nature analogic. It is passed in digital format conversion using A-N the purpose of conservation, processing and transmission bandwidth communication channels high. Analog and digital signals are used to transmit information, usually through electric signals. In both these technologies, the information, such as any audio or video, is transformed into electric signals. The difference between analog and digital technologies is that in analog technology, information is translated into electric pulses of varying amplitude. In digital technology, translation of information is into binary format (zero or one) where each bit is representative of two distinct amplitudes. http://http://www.diffen.com/difference/Analog_vs_Digital/

6. Classification 3. In digital video systems: the signal obtained in the conversion step is digital. Transmission is all digitally and image formation is of course the digitall signal. http://www.ljcreate.com/products/product.asp?id=218&program=197&curr=2
