Document Summary
A fourth-order (n = 4) chebychev low pass filter is implemented using two. = 1 db and the passband frequency, p = 1000 rad/sec. C, q & k of each stage, and the component values r1, rf1, r2 & rf2 for this 4th order filter. (refer to appendix for more information) Q3. b [4 marks] for a particular filter implementation, c = 8. (r1r2c1c2)-1/2 . Determine the sensitivity of c to c1 , i. e. w. Q3. c [6 marks] assume all components to be ideal. For a d. c. voltage of 1 volt applied to the input of the switched-capacitor circuit shown below:- [2 marks] what charge is transferred for each cycle of the two-phase clock? (ii) [2 marks] for a 100 khz clock, what is the average current drawn from the input source? (iii) Ele514-mid term exam fall 2004 6 of 9. [25 marks] consider the wein-bridge oscillator circuit as shown below.
