WebThe center frequency will be 2 KHz. The bandwidth will be -3 dB of 200 Hz. Take capacitor value as one uF. So, fN = 2000 Hz, BW = 200 Hz, C = 1 uF. At first calculate the R. R = 1 / 4π fN C, R = 39.78 ohm. The Quality factor: Q = fN / BW = 2000/200 = 10 The value of feedback function: K = 1 – (1/ 4Q) Or, K = 1 – (1/40) Or, K = 0.975 tape down meaning https://artworksvideo.com
