IND 400 Lecture 9: Work Sampling

A bandpass filter passes signals with frequencies that are within a certain range.In this filter the ratio of the magnitudes of the voltages is given by:
RV=V0/Vi=wRC/sqrt(1-w^2LC)^2+(wRC)^2 where w is the frequency of the input signal.Given R=1000ohm,L=11mH and C=8µF,determine the frequency range that corresponds to RV>=0.87.
Using MATLAB:
a) First plot the graph
b)Use matlab to construct a script for the Bisection method and Newton's method to find one of the possible roots.

Match the heat transfer process in ‘A B C’ to ‘P Q R.’

1. Conduction

2. Convection 

3. Radiation 

 P. Heat transfer from one molecule to another molecule

 Q. Heat transfer does not require a medium

 R. Heat transfer through a fluid.
