Write the transfer function for a first order lowpass filter with a 3dB down frequency of 9kHz and a DC gain of 5db. Sketch a Bode (straight line) plot of the frequency amplitude and phase response for the transfer function: 2-1. Label all points including cutoff frequencies and magnitudes in db. 2-2. How would the transfer function change if I wanted a high Q gain at 4kHz? 2-3. Draw a schematic of the circuit.
