Anything and everything is being counterfeited. For the longest time gold 
coins (American Gold Eagles) were a safe bet but now there's even fake 
bullion that's out there.

Even devices (Gold Coin Balance) that for years were a simple test for 
authenticity can now be fooled by these counterfeit coins. Real American 
Gold Eagles still pass the "ping test" which appears to be the only personal 
device remaining that can tell a real from a fake.

New Counterfeit Bullion in the Diamond District?
29 January, 2014

Recently, we had a counterfeit American Gold Eagle (official bullion coin of 
the United States) come into our storefront. By using our expert assaying 
techniques, we found that the coin was actually gold-plated tungsten. Since 
tungsten and gold weigh the same, these types of counterfeits can be 
difficult to detect.

NEWS FLASH!!!
Goldcoinbalance.com has discovered a fake Gold Eagle one ounce that passes 
the tests for weight, size and thickness. Our GoldCoinBalance Guarantee has 
always stated that we would pay the spot gold price for any gold coin that 
passes all three tests of the GoldCoinBalance. We were so confident in our 
product's ability to spot the fakes we offered this guarantee. However, we 
recently received a coin and letter from a customer who had purchased a Gold 
Coin that passed the tests, but was a FAKE Tungsten Coin. So unfortunately, 
we can no longer buy Kugerrands or American Eagle Gold Coins that pass the 
Goldcoinbalance tests. Someone is making Tungsten core fake coins that do 
pass the test!!! Buyer Beware!!


Here is the letter we received from a customer

Dear Jared,

"First let me say the Gold Coin Balance is a great tool and has helped to 
easily identify over 10 gold coins as real in just a few seconds. It has 
also helped me to identify 3 fakes along the way too. The tool has saved me 
from being scammed for over $3,500. The reason I am sending this 2003 
American Gold Eagle to you is because it passed all 3 tests on the Gold Coin 
Balance, but still does not look 100% correct.

"To make systems stable, we use Negative Feedback"

"Since it's hard to make the op-amp gain stable over all operating 
conditions *negative feedback* is used to **stabilize** the op-amp"

"Negative feedback is a central concept in the design of linear amplifiers. 
It enables them to be designed with predictable, precise and **stable** 
performance."

Negative Feedback
A major breakthrough was invention of the feedback amplifier in 1927 by 
Harold S. Black. Black used negative feedback which reduces the gain but 
makes the amplifier very insensitive to variations in tube characteristics. 
This invention made it possible to build **stable amplifiers** with linear 
characteristics.


Positive Feedback
In a system with positive feedback, the increase in some variable or signal 
leads to a situation in which that quantify is further through its dynamics. 
This has a **destabilizing** effect and is usually accompanied by a 
saturation that limits the growth of the quantity.

<quote>
If we introduce positive, or regenerative, feedback into an amplifier 
circuit, it has the tendency of creating and sustaining oscillations.

Negative feedback, on the other hand, has a "dampening" effect on an 
amplifier. While positive feedback drives an amplifier circuit toward a 
point of instability (oscillations), negative feedback drives it the 
opposite direction: toward a point of stability.

OSCILLATORS

We have already talked about FEEDBACK in terms of NEGATIVE FEEDBACK to 
stabilize a circuit. We will now cover a new term called POSITIVE FEEDBACK - 
it changes the performance of circuit completely. It makes the circuit 
OSCILLATE. Negative feedback "kills" a circuits performance - positive 
feedback makes it oscillate.
