Description

This is the pair block of UPSMPL_c block. It realizes a decrease of the sampling rate of the input, by taking one element among M, where M is the downsample factor.

Dialog box

• Size of outputs
  Type 'vec' of size 1. integer . The size of the regular output port.

• Downsample factor
  Type 'vec' of size 1. The down sample factor

• Offset
  Type 'vec' of size 1. The initial value of the discrete counter, gives the offset of the first input sample.

• Inherit (no:0, yes:1)
  Type 'vec' of size 1. Herits events by its regular input ports (disable the event input port).

Default properties

• always active: no
• direct-feedthrough: yes
• zero-crossing: no
• mode: no
• regular inputs:
  - port 1 : size [512,1] / type 1
  
• regular outputs:
  - port 1 : size [64,1] / type 1
  
• number/sizes of activation inputs: 0
• number/sizes of activation outputs: 0
• continuous-time state: no
• discrete-time state: no
• object discrete-time state: no
• name of computational function: sousecht
