What is pulse transmission?
In pulse transmission systems, pulses modulated in various ways to carry information may be transmitted by amplitude, phase or frequency modulation of a carrier, and with each type of modulation various methods of detection are possible.
Are digital signals transmitted as pulse?
Digital signals are transmitted to computers in the form of electronic signals sent as pulses.
How pressure pulse is transmitted in the peripheral arteries?
The sudden expulsion of blood from the ventricle to the aorta in every systolic ejection produces a pressure wave that propagates along the arteries to the periphery, called a pulse wave or arterial pulse.
What kind of filter is used for pulse shaping?
There is a type of filter commonly used to meet these requirements. It is called the “raised cosine filter”, and it has an adjustable bandwidth, controlled by the “roll off” factor. The trade-off will be that the bandwidth of the signal will become a bit wider, and therefore more frequency spectrum will be required to transmit the signal.
What is the purpose of pulse train shaping?
Pulse train shaping allows the energy and/or width of each of a group of laser pulses to be delivered sequentially. This allows the energy input from the laser to be tailored to the specific application.
When does a pulse shaping filter have zero response?
The pulse shaping filter should have a zero response at intervals of T in time so that a given symbol’s pulse response will not have a contribution to the signal at the sampling times of the neighboring symbols.
The computers’ digital output lines often control relays that switch signals or power delivered to other equipment. Similarly, digital input lines can represent the two states of a sensor or a switch, while a string of pulses can indicate the instantaneous position or velocity of another device.
