It makes a difference for a zero ohm termination = tail. Changing the tail, the starting value for evaluation, of a 100 term ladder... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.Which circuit are you simulating with 100 stages? Our original ladder in post #1 or your ladder? Not sure what you mean by “changing the... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.Welcome to PF! I believe you are solving a different ladder that goes like this: The ladder being studied in this thread has the... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.Here are recursion relations that give the exact polynomials for the numerator and denominator for any ladder with ##N## stages and a... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.Doing that derives the limiting term as ##0.9⋅10^n## discussed in post #8. -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.I believe if it’s transcendental it is also irrational. -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.And it may be rational, irrational and if irrational it may be expressible as a compact, exact quantity involving a square root or it... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.For the original infinite ladder in post #1 I have found that the number of digits in ##p## and ##q## goes as ##1+n(n-1)## as in post #5... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.BTW, the reverse ladder, where the horizontal resistors are large and the vertical resistors are small, converges super fast with no... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.I’m not sure what you mean. It makes a big difference what value I pick for the infinite termination. The value of ##0.9⋅10^n## is not... -

The thing I find about continued fractions, and ladder attenuators, is that evaluation from right to left attenuates the numerical... -
bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.I have found that this continued fraction converges rather slowly. As ##n→∞##, the horizontal resistors become vanishingly small and the... -

bob012345 replied to the thread Undergrad Non-Linear Infinite Resistor Ladder.Thanks. In looking at the exact solutions for the first few terms it seems the fractions quickly get gigantic. These seem also to have... -

Simply fixed value ladders always do converge to a recurring continued fraction, and since an RCF can be evaluated with a quadratic...
