1. Derive the transfer function vout / vin for each of the filter circuits given in tin FIGURE 1 and sketch Bode plots for each circuit (amplitude and phase).
2. (a) FIGURE 2 shows the response of a first-order filter to a step input. Estimate the half-power cut-off frequency of the filter and sketch its frequency and phase response.
(b) Select (with justification) from the op-amps listed in TABLE A those which are NOT suitable for use as the active component in the filter of (a) above.
