Answer #1

A) Interpolation and the decimation are importatnt for digital signal processing. Interpolation is used for increase sampling rate in the system while decimation isused to reduce sampling rate in the system.When we require high sampling rate then we use Interpolation and to down sampling rate we use Decimation. It minimise cost for system.Examples are it is used in band pass filters. FIR Filters

B) Noise=> Noise is unwanted signal present in system because of which system not giving desired response.

Interference => Interference is signal distorted while travelling from one location to another location.

jamming => jamming stops total communication of signal, because of this there is problem for sending signals

Repeaters are often used on both analog and digital communication systems to eliminate noise. True false When determining the decibel value of the signal-to-noise ratio (SNR), both the signal and noise floor power must be referenced to the same power units (i.e., both referenced to 1 watt or 1 milliwatt, etc.). True False Select the correct statement(s) regarding delay skew. a. delay skew impacts all conductive guided mediums (e.g., UTP, coaxial cable, etc.) b. delay skew only impacts fiber optic...
