Pulse Position Modulation Applications. This is so because information content is present in the position of the pulses rather than amplitude. Advantages of pulse position modulation.
This is repeated every t seconds such that the transmitted bit rate is bits per second. The pwm signal is applied to pin no 2 through the diode r 1 c 1 combination. Advantages of pulse position modulation.
Pulse modulation is a type of modulation in which the signal is transmitted in the form of pulses.
Thus the input to pin no 2 is the negative trigger pulse which corresponds o the trailing edges of pwm wave form. In pulse duration modulation pdm the amplitude of the pulse is kept constant and only the variation in width is noticed. Pulse modulation can be classified into two major types. It is primarily useful for optical communications systems which tend to have little or no multipath interference.
