1. A telephone channel using copper wires can be modeled by a simple RC filter. Sketch a circuit showing a resistance Rand a capacitance C that models this channel and use a Laplace or Fourier Transform method to show that the frequency response of this channel is given by: 1 H(f) = 1+ j2#ƒRC and state (without proof), what is the absolute bandwidth of this channel.
