a) A filter, made with a capacitor and a resistor R, is to pass frequencies in the audio frequency range but attenuate a sinewave signal with a period of 80 ms. (i) Identify what type of filter is required and draw the circuit diagram of the filter showing the input and output terminals. (ii) If R is 10 k, which one of these three capacitors would be the most appropriate value to use in the filter design: 300 pF, 30 nF or 0.3 μF ? Show any calculations you have made.
