Tip of the Month
Measuring the output resistance of a running transmitter
Here is a cool way of measuring the resistance seen at a given node by injecting a small-signal sinusoidal current into the node and measuring the resulting change in its voltage.
Primitive of the Month
meas_value
This primitive measures the value of an xreal-type signal at the specified triggering event and produces a real-type output.
