ASC Filter Change

Alexa, Matt

In an attempt to get stable, if low-bandwidth, loops, we made some cut-off filters.

The new ASC filter in FM5 is:

LP0.2 zpk([0.0025+i*0.499994;0.0025-i*0.499994],[0.1+i*0.0979794;0.1-i*0.0979794;0.05+i*0.193649;0.05-i*0.193649],1,"n")

A couple of old filters that got lost were:

ASC_PRC1_Y FM5 "res1.35" resgain(1.35,10,10)resgain(3.16,10,10)
ASC_MICH_P FM5 "LP15_new" ellip("LowPass", 4, 1, 20, 15)cheby1("LowPass", 2, 1, 100)gain(2, "dB")
