## Builds a band pass filter.
# @param gain Filter gain in the passband (linear)
# @param Fs Sampling rate (sps)
-# @param freq1 End of stop band (in Hz)
-# @param freq2 Start of pass band (in Hz)
+# @param freq_sb1 End of stop band (in Hz)
+# @param freq_pb1 Start of pass band (in Hz)
+# @param freq_pb2 End of pass band (in Hz)
+# @param freq_sb2 Start of stop band (in Hz)
# @param passband_ripple_db Pass band ripple in dB (should be small, < 1)
# @param stopband_atten_db Stop band attenuation in dB (should be large, >= 60)
# @param nextra_taps Extra taps to use in the filter (default=2)
# spinning it up to the right center frequency
