PAM is simple but susceptible to noise, PWM is efficient and used in digital communication, and PPM is resistant to noise and often used in wireless communication. To simulate these signals, you can use software like MATLAB or Python with libraries such as NumPy and SciPy. Apply the ...
In this work, we compare 4-pulse amplitude modulation and on-off keying modulation formats at high speed for short-range optical communication systems. The transmission system comprised a directly modulated vertical-cavity surface-emitting laser operating at a wavelength of 850 nm, an OM3+ multimode...

In acommunication system, the modulation is an important step. Modulation is the process of transmitting a message signal (Baseband signal with low frequency) from transmitter to receiver without changing its characteristics (like amplitude, frequency, phase) by using a carrier signal (high frequency...
A metro network is used to connect hosts, databases, and LANs in different places across a city. It is a high-bandwidth, multi-function, and multi-service multimedia communication network that integrates data, voice, and video services. The interface bandwidth of such a network directly determine...
The present invention relates to a module for detecting an output of the PAM in the mobile communication terminal, and more in detail the load The PAM outputs detection module and the mobile communication terminal is disclosed with a load switch for the principles of the switch by using a volt...
Today communicationis the heart of technology. Communication is achieved over a transmitter and a receiver through signals. These signals carry the information through modulation. Pulse Amplitude Modulation is one of the kinds ofmodulation techniquesused in signal transmission. Pulse amplitude modulation is...
