(Color online) Time frozen spectrograms comparing ideal (blue lines) and discretely sampled (red markers) modulation spectra of SMR stimuli for 33.33 (A & B) and 100 (C & D) carrier densities at 4 (A & C) and 16 (B & D) RPO. For each modulation spectra, a single octave representing the frequency range from 100 to 200 Hz is illustrated.
