So, can you help me with my math? If Cx= 1/(2πBR1) does not B= 1/(2CxR1)? Using their values for Cx (39n) and R1 (220), what is the Frequency Response?
Typically you select B, it is the upper limit frequency response of you amp. Decide the highest frequency you wish your amp to pass, say 20,000 Hz, so that would be you B.
