ECEN 2250 Circuits/Electronics 1 Fall 2007 9-12-07 P. Mathys Recitation Problem Set 3 (For Tue. 9-18-07 recitation session) 1) The following circuit is a resistive T network. It is a 2-port device with 4 terminals (as opposed to a 2-terminal device like a single resistor). R X R Y R Z - v 1 + - v 2 + i 1 →← i 2 T network The two terminals on the left (with voltage v 1 and current i 1 ) make up port 1 and the two terminals on the right (with voltage v 2 and current i 2 ) make up port 2. The most common use of this device is with a voltage source connected to one port and a load resistor connected to the other port as shown in the next schematic. + - R X R Y R Z - v 1 + - v 2 + i 1 i 2 v 1 R L i L T network In this case the T network attenuates the input voltage v 1 (or the input current i 1 ) so that the output voltage v 2 is smaller than v 1 (or the load current i L is smaller than i 1 ). A simple practical use of this is to make an audio signal (e.g., from a power ampliﬁer) less loud or less powerful (e.g., to feed it into the microphone input of a recording device). A single i
