1.1 The First Generation

The first generation was very primitive. Each Ns microphones were put in parallel. So the output signal was the sum of each microphone. the figure [*] illustrates this.

In this case the beamforming was done analogically and at $90\deg$ of the center. The result is a single output analogic signal as seen on the overview of the microphone array first generation in figure [*].
