Hi Friend
Firstly, I wanted to wish you a happy Thanksgiving if you celebrate it.
In America, this is a popular week to take a vacation from work, eat a
ton of food and watch alot of football!! :)

Secondly, I stumbled onto a great article about impedance and
how it relates to true bypass that I think you may enjoy:

Have a great week, and Thanksgiving if it applies!

Talk to you later,
Brian
