Hi All,
The speed control input on my DC motor controller is an analogue signal ranging from -10V to +10V. When i look at the waveform on a scope it is awfully noisy and contains some high frequency spikes.
Can anyone recommend a way to remove the noise/spikes? Its difficult to say what frequency the nosie is, my scope does not have any advanced features.
thanks
