Step 1 of 3 11.013P Consider the following data: 1% The formula for the change in closed loop gain is, 1 = 1 10 = 9 Step 2 of 3 Calculate the closed loop gain. Consider that = Therefore, A=25(10) = 250 V/V Now, calculate the lowest gain. 10% = 25 = 225 V/V Hence, the lowest gain of the amplifier is 225 V/V The nominal gain of the amplifier is 250 V/V Step 3 of 3 Calculate the feedback factor (B). 9 = 250 =0.036 Therefore, the required feedback factor is 0.036
