WebThe experiments were conducted with transducers in a variety of different positions, and amplitude-modulated ultrasonic signals were used with four different envelopes. The algorithm was capable of correctly classifying over 96% of narrowband signals with severe multipath effect at low computational cost. WebEnvelope Peak External Decay. The Envelope Peak External Decay algorithm measures the absolute peak level of the incoming signal. A hold time is applied that will hold the value of an incoming peak level before starting the decay ramp. The decay ramp is linear and its speed can be controlled using the Decay Speed control input pin.
