In Resistor combinations: How many values using 1kohm resistors?, Glen Chenier showed us how many combinations of resistor combinations you can get. Many people commented, trying to develop a formula ...

When available fixed-gain values match design requirements, a PGA (programmable-gain-amplifier) IC offers a drop-in choice, but what does a designer do when a suitable PGA is unavailable? Before the ...

[jefffolly] published some straight forward plans for a passive volume control. It uses a resistive ladder built across the contacts of 12W rotary switches. Each resistor provides a 5dB difference, ...

(ladder Digital to Analog Converter) Circuitry used to convert digital sound back into analog form for amplification. An individual resistor is associated with each bit of the digital sample, ...

You are looking at the input port of an infinite ladder circuit with a common ground node. All resistors have the same resistance R. What is the equivalent resistance you see? Replace all resistors by ...
