Lesson 19 Flashcards
The Zeta Noise blocker was
an example of a hybrid analog-digital hearing aid
The first commercially available Digital Signal Processing hearing instrument
included a body-work electronic processor
A programmable hearing instrument with 4 channels and 1 memory could be considered a ______programmable hearing instrument
Class 3
In digital signal processing, a set of mathematical steps involving multiplication, addition and subtraction is referred to as
an algorithm
The number 512 would have a binary code of
1000000000
Quantization is related to
number of bits
The number of bits impact the
dynamic range of the hearing instrument
The sampling rate
refers to how often the waveform amplitude is measured, has a direct bearing on frequency bandwith of hearing instrument, must be at least twice as fast as the highest desired frequency
Imaging occurs during the
digital to analog conversion stage
Which of the following is not an advantage attributable to digital signal processing in hearing instruments
use of active filters for frequency response shaping
