Hi Jose,
yep, multiply const with a real value |·| < 1 would be **equivalent** to an analog attenuator.
anyway, it's very uncommon to do such an operation in DSP, unless you need a fair comparison between different signals or such.
Maybe you'd want to explain why you want to do that?
Best regards,
Marcus

Hello,
This may seem like a really simple question, but If I wanted to attenuate my signal coming out from a USRP source block in GRC, say by 80 dB,, how would I go ahead and do that? Would I just add a multiply constant block after my USRP source block to scale down the incoming signal's amplitude? Would I be able to check my attenuated signal through the QT frequency plot block?
Thanks,Jose
