Well, I don't think this solution using vector works (I might be wrong,
of course). I tried to build it in the latest version of Gnuradio which
is 3.7.2.1 (Ubuntu 14.04 LTS). The prints are shown below:

The blocks:

Input signal:

Output Signal:

Vector created:

What I need to do is a kind of "switch". With this vector in the Ctrl
Port of the Sample & Hold, I want the same wave of the input in the
output, but appearing and desappearing according to the Vector Source (0
- no signal, 1 - entire signal).

If the signal in the Input Port is a square wave, then I want the same
wave but appearing and desappearing in a random way according to the
vector I created, but It isn't happening.

I don't know if I was clear enough. Please, help me and tell me if you
need more details about my problem.

Sorry and thank you.
