How many Htz is a typical myoelectric signal
|
60 Htz
|
|
|
What is notch filtering?
|
Taking out the energy around 60 Htz so that other signals are less likely to operate around 60.
|
|
|
What is rectification?
|
Turns negative signals and makes them positive. CHANGES there polarity but retains the signal energy.
