Asymmetric pulse shapes with long delayed phases are more electrically efficient than symmetric pulses
Evidence
The effect of pulse shape was highly significant (F(3,18) = 22.76, p < 0.001). RPS-IPG required 2.2 dB less current than SYM (p < 0.05) while TRI required 2.7 dB more. There was no significant difference between SYM and RPS. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2319
