Masking of RF Timed Signal

Hi All,

I have a baseband timed signal, which modulates a RF timed signal.

There are instances where the basband timed signal will be zero, and for those instances, I like to "mask" the RF timed signal, ie set the RF signal to zero.

May I know how I should do that?

No one else has this question

Take the absolute value of the baseband signal and compare it against a small threshold, e.g. 1.0e-6, using the TestLE component. The threshold can be generated by a Const component. Connect the output of Abs and Const to the TestLE inputs in a way so that when the signal is smaller than the threshold the output of the TestLE is one (you could use TestGE and swap the two inputs). Then use MultiplierRF to multiply your RF signal with the output of the TestLE component.

Hi kkladopo,

Thanks for the suggestion. It works with a TestGE.
