A transistor output noise voltage is measured at 15microvolts when the standardized noise source is at the input. With the noise source removed, a noise voltage of 5 microvolts is measured. Calculate the noise figure.
2. Derived the formula of output signal to get the equation of Noise?Current gain In the same way, when power gain is calculated using current instead of power, making the substitution , the formula is: 3. In many cases, the input and output impedances are equal, so the above equation can be simplified to: 4. This simplified formula is used to calculate a current gain in decibels and is equivalent to the power gain only if the impedances at input and output are equal. 5. The "current gain" of a bipolar transistor, or , is normally given as a dimensionless number, the ratio of to (or slope of the -versus- graph, for ). An amplifier has an input impedance of 50 ohms and drives a load of 50 ohms. When its input () is 1 volt, its output () is 10 volts. What is its voltage and power gain? 8. Voltage gain is simply? 9.
