D)two cascaded RC circuits.

Question

Quizplus · Accepted Answer

In a filter circuit, a single pole refers to a single RC (resistor-capacitor) circuit. A single pole filter is a type of passive analog filter that only has one reactive component and one resistor, thus having a transfer function with a single pole in its frequency response. This type of filter typically attenuates low-frequency components of a signal while allowing higher frequencies to pass through with minimal loss.
