DFIR – Discrete finite input response filter

Block SymbolLicensing group: ADVANCED

Function Description
The DFIR block is a filter whose impulse response (or response to any finite length input) is of finite duration, because it settles to zero in finite time. The calculation takes place in the form of a convolutional integral (sum) - the impulse characteristic is entered in the hk field already in discretized form for the correct period.

Input

u	Analog input of the block	Double (F64)
R1	Block reset	Bool
HLD	Hold – the block code is not executed if the input is set to on	Bool
u0	Initial input value (fill buffer)	Double (F64)

Output

y	Analog output of the block	Double (F64)
RDY	Ready flag	Bool

Parameters

nmax	Allocated size of array $↓$ 10 $↑$ 10000000 $⊙$ 100	Long (I32)
hk	hk $⊙$ [0.6 0.3 0.1]	Double (F64)
