# An COTS solution for delaying a 120kHz analog signal?

Looking for some cheap method of adding a 350uS delay to a pulsed sine wave. It would be useful to emulate a pitch-catch ultrasonic distance measurement setup

• You mean like a delay line? – Ignacio Vazquez-Abrams Jul 24 '15 at 14:41
• "COTS solution" means that this is a shopping question, which is off-topic here. – Dave Tweed Jul 24 '15 at 15:24

• Could use a <$2 MK02FN64VFM10 which has 1.2MSPS 12-bit ADC and 12-bit DAC on-chip 16k x 8 RAM which is sufficient for ~6ms delay at 1.2 MBS without packing, and ~9ms packing 2 x 12 bits into 3 bytes. Of course a bit of code would be required. – Spehro Pefhany Jul 24 '15 at 19:01 • And if I put that together, and costed my company time, it would be around$2000 excluding parts and PCB layout and manufacture. Let's say an even \$3000. Hence the question. – Dirk Bruere Jul 24 '15 at 20:13
