METHOD FOR SHAPING THE SPATIAL RECEPTION AMPLIFICATION CHARACTERISTIC OF A CONVERTER ARRANGEMENT AND CONVERTER ARRANGEMENT |
摘要 |
So as to shape the spatial amplification characteristic of an acoustical to electrical converter arrangement at least two sub-arrangements (I, II) of converters are provided, generating different spatial amplification characteristics. Frequency domain converted signals (S1) which are proportional to the output signals of the sub-arrangement are compared in a unit (39) on respective spectral frequencies (fs) and there is generated at the output of the comparing unit (39) a binary spectral comparison result signal (A39). Signals (S2) which are as well proportional to the output signals of the sub-arrangements (I, II) are fed to a switching unit (41). For each spectral frequency (fs) the control signal from unit 39, as a binary spectral signal, controls the spectral amplitude of which of the two input signals (S2) is passed to the output (A41) of the switching unit and of the arrangement.
