None

1

S12

Reverse transmission coefficient, complex number: 1 + j × 0, polar(), dbpolar()

None

1

S11

Port1 reflection coefficient, complex number: 1 + j × 0, polar(), dbpolar()

CheckPassivity

Check passivity flag: if set to yes, a passivity check is performed and a warning is output if the device is not passive; if set to no, a passivity check is not performed.

None

yes

Delay

Time delay

 

 

Notes/Equations
  1. Use the functions polar( ), dBpolar( ) to represent the S-parameters in terms of magnitude, phase or dB, phase.
  2. The block parameters must be passive for the noise performance to be as expected.
