Limiters

The Limiters can be used to restrict an output to values between

a set of specified ranges. These parts are described below.

LIMIT

The LIMIT part constrains the output voltage to a value between

an upper limit (set with the HI attribute) and a lower limit (set

with the LO attribute). This part takes one input and provides

one output.

GLIMIT

The GLIMIT part functions as a one-line opamp. The gain is

applied to the input voltage, then the output is constrained to the

limits set by the LO and HI attributes. This part takes one input

and provides one output.

SOFTLIMIT

The SOFTLIMIT part provides a limiting function much like the

LIMIT device, except that it uses a continuous curve limiting

function, rather than a discontinuous limiting function. This part

takes one input and provides one output.
