OTDM
in the hybrid networks or simple ioptical time divison multiplexing.
there we use single wavlength and modulate it with different data, how to provide the to them so that it will lead to faithfull time divison multiplexing.
what should be delay , is there any pattern or formulla for that.
with regards

Hello Sahil, Bessels function is just a mathematical trignometric function. It is used for solving the equations that contain trignometric functions with in a function…It is frequently used in electronics and signal processing .
It is a type of analog linear filter with a maximally flat group/phase delay (maximally linear phase response), which preserves the wave shape of filtered signals in the passband. Bessel filters are often used in audio crossover systems.
In all these applications if the mathematical equation generated have trignometic functions as a function of trignometric function then Bessels function can be used in solving them.
Hope you query has been answered.

Hello Abid, Asif , Sahil, tanweer and umer.
I think the attached pdf will help you to solve the query.

Hello everyone interested in the discussion titled “OTDM”. My question is that can we transmit the signals at wavelength lanbda1 and another signal having wavelength lamda2 through the same channel with different data rates datarate1 and datarate2 respectively?

Hello tanweer i have one query. As you have mentioned in one of your comment that “several optical signal modulated at the bit rate B using the same carrier frequency are multiplexed optically to form a composite optical signal at a bit rate NB, where N is the number of multiplexed optical channels.” Can we conclude the data rate of the complete signal be different from the individual data rates of different signals multiplexed??
