M E 345 Spring 2008 Professor John M. Cimbala Lecture 21 03/03/2008 Today, we will : Review the pdf module: Review of Basic Electronics Do some example problems – basic electronics Review the pdf module: Filters If time, do some example problems – Filters Example Given : A bunch of 10 k Ω resistors is available in the lab. We have need for a resistance of 22 k Ω for a circuit we are building on a breadboard. To do : Figure out how to create the required resistance from the available resistors. Solution :

Solution : V 1 V 2 R 1 R 4 R 3 R 2 Example Given : A voltage signal has a DC offset. We want to remove the DC offset so that the frequency content of the AC (fluctuating) component can be analyzed. To do : Figure out how to remove the DC offset with a single electronic component (i.e., one resistor only , or one capacitor only , or one inductor only , etc.). Solution : Example Given : In the circuit shown, V in = V p sin( ω t ) – a pure sine wave (AC voltage). To do : Calculate V out . Solution : V in R C V out...
