Does GNUradio have an envelope detector block?

Now I’m trying to build an ASK demodulator. I use GRC.

However, I REALLY REALLY couldn’t find an envelope detector.

Does GNUradio have an envelope detector block?

Or, do I have to make that one?

The RMS block will basically do what you want, you can play with the
alpha parameter to
give you control over the low-pass corner frequency of the envelope
detection.

gr_complex_to_mag will produce the envelope of an amplitude modulated
carrier.
