What are composite signals why you needed?
In case of TV broad casting, the Video Signal is not transmitted alone, but it accompanied by a number of other signals or pulses, which help the exact reproduction of the picture at the receiving end. These pulses include Blanking Pulses, Synchronizing pulses and Equalizing pulses. A combination of Picture signal and other Controlling signal or pulses is called Composite Signal. Thus Composite Video Signal may consist of Following Parts.Picture information (Data)Blanking Pulses (Delay Pulses)Vertical and Horizontal Synchronizing Pulses (controlling Pulses)Generally,A Combination of Data and Other Controlling Signal is Called Composite Signal .
What is converter transformer and what its function in HVDC transmission?
It is a transformer that is made for the converters. It is (usually) wired with a Wye AND and Delta output. This allows the transformer to output a total of 12, 30 degrees out-of-phase pulses. This gives rise to many advantages with filtering, efficiency, etc...
What do lasers convert electrical signals into pulses of?
coherent light
Why are synchronizing pulses transmitted along with the picture signal?
To keep the picture locked on the screen, without the synchronization pulses it would become unstable and roll, shift, and tear making the picture impossible to view.
What are signals composed of pulses of precise positive voltages and zero voltages?
Digital
