What is the sampling frequency of the accelerometer?
The accelerometer is attached to a platform that moves across smooth, gravely and then large stepped surfaces at random times. I do not have access to the accelerometer datasheet I only know the sampling frequency. The dataset contains accelerometer data (a_x) and a time, which is in seconds. The sampling frequency is 100 hz.
How to filter accelerometer data from noise?
Attached is a plot of accelerometer data with 3 axis. The sudden bumps in the plot are the noise. I would like to get rid of them. So what filter should be used in this case ? If it is possible provide some pseudo code for it and explanation.
Which is the best filter for acceleration data?
The acceleration data certainly needs a different filter than the one you have used here.The force data looks okay, but not sure how you have filtered. Is this with a 300 point moving average?
How to calculate speed and distance from a 3 axis accelerometer?
Calculating Speed and Distance from a 3-axis accelerometer? Have integrated a 3 axis accelerometer on a microcontroller in order to calculate speed and distance. So far my experimental data is off by a factor of 3. Any ideas of some good algorithms to implement?
How many samples per second does a sinewave have?
Take a simple sinewave with a frequency of 1 Hz and a duration of 1 second as shown in Figure 1. The signal has 128 samples and therefore a sampling rate of 128 samples per second. Notice that the signal ends just before 1.0 seconds.
Which is frequency corresponds to half the sampling rate?
The frequency which corresponds to half the sampling rate is known as the Nyquist Rate. [Note also that the amplitude is 0.5, exactly half the amplitude of the signal in Figure 1. This half amplitude is an effect of the type of frequency transform that has been used.
This is no coincidence and is carefully selected by DATS. The frequency which corresponds to half the sampling rate is known as the Nyquist Rate. [Note also that the amplitude is 0.5, exactly half the amplitude of the signal in Figure 1. This half amplitude is an effect of the type of frequency transform that has been used.
