Radio Shack DSP-40: A Review
http://www.redwaveradio.com/11_82d22c285e228014_1.htm
The manual recommends buying a Radio Shack wall wart. The noise reduction filter is nothing more than a low-pass audio filter. The stated specs for this filter are: WIDE 200-2950 Hz. MED 200-2500 Hz. NARROW 200-2000 Hz. In the short few hours I have had to play around with this, I am impressed with its ability to notch out heterodynes.

See the QST review and Radio Shack's admission of that. What it does do is seem to reduce noise because of its dsp filtering. It is a handy little audio amp, and a filter and it will boost the signals of some of the radios that it is used with.

Radio Shack DSP40 Modification Unfortunately this simple audio DSP filter has several shortcomings, but the good news is that some can be corrected and some can be mitigated. I bought two of these filters to experiment with, one to modify and one to use as a reference, when Radio Shack closed them out. I

The RS DSP-40 is a simple, low cost digital signal processor audio filter. Like other audio filters, it reduces, but does not eliminate noise on the audio output of your receiver or transceiver. It is not as good as a Timewave DSP-zx, but you can generally get one for one tenth of the cost of the Timewave product. No DSP audio filter will cure ...

SDR's are 100% DSP, that's what they are and how they work. If you're asking if they have the same sophistication in things like filter implementations or noise reduction algorithms tailored for ham use that depends on the specific SDR software but SDRs by definition are built on DSP technologies and are in fact DSP devices.
