A first end of the threaded spindle that is remote from the first rotary bearing, projects into a tubular section of the extension arm, irrespective of a position in which the extension arm is situated. The tubular section extends with a constant internal cross-sectional shape along the axis of rotation.

Abstract: Systems and methods for producing a linear-phase digital FIR filter from two sub-filters for an audio signal. In one method, the sub-filters are provided as sub-sets having numbers of coefficients, a lower cutoff frequency of the particular sub-filter being greater than the sampling frequency of the audio signal divided by the number. The sub-sets are linearly convoluted with one another so as to form a total set having a number of coefficients greater than the numbers, and the total set is symmetrically reduced to a number less than the number, so as to form a reduced total set of the filter. A linear-phase digital FIR filter for an audio signal is created by the method.
