What is Noise in Communication? A broad definition of noise in communication is something that keeps a receiver from completely comprehending a message. Distractions can inhibit a person from offering his undivided attention and may keep him from fully grasping what you are trying to say.
Difference Between FDM and FDMA. Frequency Division Multiplexing, or FDM, is a multiplexing technique for the physical layer that allows multiple low bandwidth signals to share the same high bandwidth frequency range. It is achieved by allocating a smaller frequency range to each signal that is using the same channel.
The major difference is that, a DSP is a chip which can be programmed based on our requirement, whereas an FPGA can be programmed to design a chip for our own purpose. FPGA ca â¦ n also be reprogrammed based on the changes in our application. 6 people found this useful.
