The amplifier consisted of a second order, three-level modulator, an H-bridge power stage, and a second order, passive Butterworth filter. Testing confirmed that the efficiency, THD, and power specifications were met in the revision of the design."|"" |"" |"" |"" |"http://rightsstatements.org/vocab/InC/1.0/"|"" |"Worcester Polytechnic Institute"|"2008-04-18" |"" |"" |"E-project-041808-145643"|"" |"" |"" |"" |"W/"22a30f7e08a8e0afabb5ac9fa1f3cbf6760d8b59""|"https://digital.wpi.edu/show/rv042v78f"
