Audio filter test & measurement with the DrDAQ

Audio filter test & measurement with Picoscope & DRDAQ

Similar frequency response measurements at audio frequency with wideband noise are also possible with the DRDAQ, as shown in the enclosed PC screens. The only problem with the DRDAQ is 50 Hz & harmonics pick-up (as apparent from the screens) due to the fact that it is not shielded, but is is not difficult to place this unit in a metal box.
