    When I first started in Electronics many years ago I remember my boss saying his mate built a blocker to stop the pubs disco next door got to loud.

    I dont know if it was a noise cancelling device because he lived next door. Or maybe a tone generator that was amplified by the disco amps.

    When they turned it down - he left them to it.

    This has always intrigued me. Unfortunately I went on to learn digital electronics, and have done hardly any r/c or filter circuit theory.

    With all these mobile phone blockers and easily made radio broadcast blockers I wonder how he did it?

    Always bugged me!

    The disco must have found it really weird as it would have only happened at that pub!

    Hopefully something different for you think about!!!
