Measuring SN audio bandpass filter circuit

Posted on Mar 28, 2007

Since the filter has a zoom function, front satin amplifier magnification such as d = 10/2. 515 = 3,97, the beam of the total, compared with 10 times magnification.

Low-pass filter parameters, according to] r five = 20k Hz, Q = 0.707, mouth if taken 0. ooiuF, you can find Gong = Rs = 7.96kQ, Lu T = iokfl (A-1) = 5.86kQ. High-pass filter parameters, ugly - 20Hz, Q = 0. 707, if cd = c5 = 0.1 liF, you can find Rs = Rt = 79, fikQO
