Project decided; worked on informative
memo

November 5, 2002
|
group divided work load; I researched
aspects of a down converter
|
5
|
November 12, 2002
|
researched aspects of down converter
|
6
|
November 19, 2002
|
went to Best Buy to research Sirius radio
equipment
|
7
|
November 26, 2002
|
setup and connected purchased Sirius
radio equipment; was successful in receiving the 'preview channel' signal
|
8
|
December 3, 2002
|
researched SMB to SMA connectors needed
to sample Sirius signal (ordered from Microwave Distributors Co.)
|
9
|
January 28, 2003
|
sampled
signal from Sirius radio equipment; realized there was no down converter
within commercial equipment; changed my part of project to bandpass filter
instead
|
10
|
February 4, 2003
|
calculated noise figure of previous antenna setup
|
11
|
February 11, 2003
|
considered possible integration schemes
|
12
|
February 18, 2003
|
read handout on Insertion Loss Method Filter Design
|
13
|
February 25, 2003
|
considered more integration schemes; preliminary design
of bandpass filter
|
14
|
March 4, 2003
|
5th order Butterworth filter design and simulation
|
15
|
March 11, 2003
|
previous equations incorrect; new Butterworth filter
design and simulation
|
16
|
March 25, 2003
|
5th order Chebychev filter design and simulation
|
17
|
April 1, 2003
|
better response of Butterworth design after changing
simulation paramaters; much better response after changing filter order to
one
|
18
|
April 8, 2003
|
filter design is essentially a resonant circuitl;
designed with microstrips in ADS
