Chapter Problem 44P Step -step solution Step Consider expression for the open circuit voltage gain decibels (dB)= Substitute 40 dB for Therefore the value of the open circuit voltage 100 V/V Step Consider circuit diagram shown Figure 1 + + Figure 1 Step Consider the expression the output voltage Substitute 100 V/V for for R. and for 500 500+100 500 =(100) 600 =(100)(0.8333) =83.33 V/V represents the closed circuit voltage gain A, Therefore the value the closed circuit voltage 83.33 V/V Step Calculate voltage gain decibels Substitute 33 V/V for A, Therefore the value the closed voltage 38.4 dB Step Consider the expression tro the power gain A, Substitute Substitute 83.33 V/V for for and for 500 =(6943.89)(2000) Therefore the value power MW/W Anonymous The equation wrong its supposed to be RO instead of RL Anonymous equation correct since finding Vo which is voltage of RL resistor not Ro Resistor Anonymous Yeah the equation was correct Step Calculate the voltage gain decibels Substitute 13.89 MW/W for 4, Therefore the value of the power 71.43 dB Comments (2) Anonymous should say "calculate the power gain" Anonymous You're right Step Calculate the root mean square value the output voltage Substitute 20mA for and for 10 Therefore the value the output voltage is, Step Calculate the value of the input voltage Substitute 7.071 for and 83.33 V/V for 7.071 83.33 Therefore the value the input voltage Anonymous Why did you randomly put millivolts Anonymous Nvm Step Calculate the value of the output power Substitute for and 500 for (7.071) 500 50 500 Therefore the value of the output power
