*1.82 Consider the circuit in Fig P1.82. You are required to make the transfer function independent of frequency. Show this is achieved by selecting C1 with a value C2(R2/R1). Under this condition the circuit is called a compensated attenuator and is frequently used in the design of oscilloscope probes. Find the transmission of the compensated attenuator in terms of R1 and R2. Figure P1.82 R2/(R1 + R2)
