A smorgasbord of analog treats awaits you as our resident Analog Guru, John Dunn, touches upon a variety of topics taken from his popular Living Analog blog published by the EDN Network on EDN.com.
Topics for this lecture include these and more:

• Control of a power inverter’s operating frequency.
• A look at telephone dial tone signals, 1954 and today.
• Birds’ avoidance of high-tension power lines.
• Gaussian probability distribution derivation.
• Bimetallic strip constructions and applications.
• Feed-forward cancellation of amplifier distortion.
• Push-pull amplifier class of operation choices.
• Worst case analysis of rail voltage decoupling.
• Microwave oven choke flange.
• Calculating octaves and decades of arbitrary ratios.
• Zero offset lowpass filter and op-amp selection.
• Low distortion but high power speaker system.
• The difference between EMF and voltage.
• The Leyden jar.
• Smith Chart mathematics.
• Transfer function trigonometric booby trap.
• Storage life of idled LED light bulbs.
• A look at the Hindenberg disaster.

Speaker Bio:
John Dunn has more than fifty years of design experience in services to over a dozen military and industrial corporations in multiple electronic disciplines including the design of analog circuits, power supplies, HF/VHF/UHF equipment, µP development and test program development.

He is the founder of the LinkedIn group Analog Developments. He is a Senior Life member of IEEE and a Ham radio licensee since 1959. He is recipient of the IEEE Long Island Section Alex Gruenwald Award and is a former Chairman of The IEEE Consultants Network of Long Island.

John has more than forty technical items published in the print trade journals. Items appearing in Electronic Design Magazine's Ideas for Design column won their Best of the Issue award on four occasions. He has hundreds of essays published in print, in the LICN blog, in the EDN Living Analog blog and elsewhere.

Agenda:
We will start our meeting at 7:00 pm. For the next 15 minutes or so, we will introduce ourselves and do a little networking. We will then start our presentation. After the presentation, feel free to stick around and chat with others to network or to further discuss our lecture topic.

NOTES
There is no cost to attend this meeting, however, if you would like to receive Continuing Education Units (0.2 CEUs/2 PDHs) then payment of a $15 fee is required (a modest increase from last year, but still a bargain). You will also have to properly fill out an Evaluation Form to prove that you attended this lecture. Click here to open the form. Simply fill it out and click on the “Submit” button.

We accept electronic payment via Zelle. Zelle is a bank-to-bank transfer mechanism supported by most banks, without a fee, as part of their normal online banking capabilities. There is also a Zelle app available for your smartphone.

When you use Zelle with your bank, it will ask for the following information: 1) the amount to send (enter $15.00), 2) what account you want to pull the money from (select whatever account you want to use), and 3) the phone number or email of the recipient (enter ieeelicn@gmail.com. Don’t worry if you see the name of our Treasurer, David Rost, pop up). If it asks for a memo field, we suggest entering "yymmdd LICN CEU” where yymmdd are the year, month and date of the lecture.

While we prefer that your payment and evaluation form are received by the day of the lecture, they must be received by the first Monday after the lecture.

If paying by Zelle is a problem for you, then please contact John Dunn at ambertec@ieee.org for an alternate payment method.
