The cap in question is part of the guitar’s tone circuit, which along with a potentiometer forms a variable low-pass filter. A rich folklore has developed over the years around these circuits ...

EMC engineers are often called on to design low-pass filters for client projects ... It's also very easy to add voltage and current “probes” throughput your circuit to monitor the performance. For the ...

A simple, widely used current limiter consists of a current sensor (usually a low-value sense resistor), a control circuit, and a pass transistor. However, this simple circuit has a limitation due ...
