"||" in Attenuators equation: ZIN = R1 + (R2 ||(R1 + Z))

ZIN = 25.97 + (35.14 ||(25.97 + 50))​

ZIN = 25.97 + (35.14 || 75.97 )​

ZIN = 25.97 + 24.03 = 50

35.14 || 75.97 = 24.03 ???



I got it!

P.S. :It's not a math symbol! Parallel resistors!
​

 

This is a common way of expressing the value of two resistors in parallel.
Use the formula for calculating the resistance of two resistors connected in parallel to arrive at the equivalent resistance.

 

I thought it was a math symbol. Right after I posted, I remembered the parallel resistors. I need to delete this thread.

Thanks anyway.
