Example:
For a gain of -3.5 dB, A
v
=10
-3.5/20
= 0.668
R7
-3.5dB
= 464 K x 0.668 = 309K9, the closest standard resistor value is 309 K.
A
v
is now 309 K/464 K = 0.666
R5
-3.5dB
= 53K6 x 0.666 = 35K7, the closest standard resistor value is 35K7.
Therefore R6
-3.5dB
is calculated to be 40K4, the closest standard resistor value is 40K2.
