Abstract
A monitoring circuit is provided. The monitoring circuit can be used to monitor signals in a cable network. The monitoring circuit includes first and second stages. The first stage has an input and an output. The input is coupled to an external circuit. The first stage scales a voltage received at its input. The second stage is coupled to the output of the first stage. The second stage has a high input impedance and a low output impedance. The second stage buffers a signal at the output of the first stage to an output of the second stage.
