Discrete Symbol Integrator block

This block is a discrete symbol integrator. The integration is done over one symbol period and
the state is re-initialized at zero for the first sample. During the integration the applied
method is just a cumulative sum of all sample values over one period :

**Size of inputs**

The size of the regular input port.

Type 'vec' of size 1.**Number of sample**

The length of the symbol in sample.

Type 'vec' of size 1.**Init counter value**

The initial sample where the discrete integration begins.

Type 'vec' of size 1.**Gain**

The gain applied to the regular output port.

Type 'vec' of size 1.**Inherit (no:0, yes:1)**

Herits events by its regular input ports (disable the event input port).

Type 'vec' of size 1.
