John: You may take a look at this article first ( https://wodewangzhishime.blogspot.com/2022/05/httpswodewangzhishime_18.html ).

Me: OK.

John: And then, there're 2 pictures above. Which one is correct.

Me: The 2nd picture is correct.

John: You're wrong. The 1st picture is correct. Let me explain to you.

.

Note: In the 1st picture, there's a circuit A. In circuit A, the frequency is strange and unbalance. The left-side branch is 90Mhz. However, the right-side branch is 100Mhz.

.

John: Because, the right-side branch is 100Mhz. As a result, circuit B is induced a electrical current of 100Mhz. And then, it is horrible.

Me: Why?

John: Read the followings.

.

1) The resonance frequency of circuit A is 80Mhz. (fc = 80) <---- fc stand for central frequency.

2) The resonance frequency of cirucit B is 100Mhz. (fc + deviation = 100)

.

John: If circuit B is induced a electrical current of 100 Mhz. Indeed, between the inductor and capacitor of circuit B, the current is just resonance. Parallel resonance is "extremely high resistance". As a result, the current can't enter terminal B.

.

if (terminal B = disabled)

{

terminal A = enable.

}

.

John: As a result, the electrical current enter terminal A. Take a look at this article. ( https://kamchihau.blogspot.com/2024/07/sequential-109.html ).
