the ispPAC10’s analog circuitry isbased on continuous-time, as opposed to switched-capacitor technology, filters implementedwith the ispPAC10 are not subject to the sampling and aliasing problems often encountered whenusing switched capacitor filters. Due to the frequencies used in the proposed experiments, it isunderstood that the sampling/aliasing problems associated with switched capacitors are far frombeing noticed, although this issue describes one feature of the ispPAC device that might beimportant depending on the application being developed. The ability to program the internalcapacitor values of the ispPAC10 allows the designer to realize thousands of distinct analogcircuits and filter characteristics from a given circuit architecture

One of the traditional tests is the modified rhyme test(MRT). It is designed by linguistic specialists in 1960’s and still used by audio and speechresearchers today [18]. MRT asks listeners to listen and select one of six words, half of whichdiffering by the initial consonants, and another half differing by the final initial consonants.
