filter parameters confusing #236

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
 {numBlocks=5, startTime=0, sampleFreq=1000.0, lowFreqStop=0, numPoles=32, highFreqPass=500.0, highFreqStop=0, bandStop=false, blockSize=15000000, filterType=[Ljava.lang.String;@91a1fa1, lowFreqPass=100, channelNames=[Ljava.lang.String;@121287b2}

is returned in Matlab for describing a bandpass filter 
where frequencies higher than 100Hz are passed and frequencies higher than 
500Hz are blocked.

Although I understand where this (lowpass and highpass) originates from, I 
seems confusing. Maybe an alternative would be 

{type= "Bandpass",  lowCutof = 100, highCutof = 500}  for bandpass
{type="BandStop", lowCutof = 50, highCutof = 70} for bandstop
{type="Lowpass", lowCutof = 100} for lowpass
{type="highPass",higCutoff = 100}  for highpass
