    "||" 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 ???

    :rolleyes:

    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.
