Readme.txt for PeteLoop.zip

PeteLoop.zip contains files pertaining to "A PLL Spur Eliminator for DDS VFOs"
By Rick Peterson, WA6NUT (QEX, July/August 2000, pp 40-49). TI-82.txt is a list of commands 
that program a TI-82 calculator to plot open-loop gain and phase response according to 
equations in Fig 14.47 of The ARRL Handbook for Radio Amateurs (p 14.44 of the 2000 
edition). The Handbook equations assume ideal op-amp gain and bandwidth, and may be 
inaccurate when designing for wide loop bandwidths. 

The ARRL Handbook is available for purchase at www.arrl.org/catalog/.
