An analysis of noise of the head amplifier in the television system
Wang Xinchu · 2004
In the television system, the head amplifier, whose low noise being put the first place in all the features, is one of the most important element circuits, which determines the image quality.Based on an analysis of the equivalent circuit and mathematical deduction, the present paper obtains a formula of signal noise ration (SNR) and thus, finds out a technique for (improving) SNR.
