It is unremarkably measured in decibels above one microvolt (or microampere) per Megahertz e.g., dBuV/MHz or dBuA/MHz.On the other hand, Narrowband Interference has its principal spectral range restrict to a specific frequency or frequencies. This type of interference is usually produced by an oscillator circuit which contains energy only at the frequency of oscillation and harmonics of that frequency. It is normally measured in decibels above one microvolt (or microampere), e.g., dBuV or dBuA.The first sources of EMI are the Ground Loop Systems in the electronic equipments like the audio / video systems. This is a common problem when connecting multiple audio-visual system components together, there is an interruption of audio signals which cause a humming noise in the audio signals and produces interference veto to picture. At times, this can eventually damage the equipment.The second source of
