The design equations for the bridged-tee attenuator
Chapter 3, Problem 3.68(choose chapter or problem)
The design equations for the bridged-tee attenuator circuit in Fig. P3.68 are R2 = 2RR2 L 3R2 - R2 L, vo vi = 3R - RL 3R + RL when R has the value just given. a) Design a fixed attenuator so that vi = 3.5 v when RL = 30 b) Assume the voltage applied to the input of the pad designed in (a) is 42 V. Which resistor in the pad dissipates the most power? c) How much power is dissipated in the resistor in part (b)? d) Which resistor in the pad dissipates the least power? e) How much power is dissipated in the resistor in part (d)?
