Linearization and Analog Signal Processing
In electronic systems that combine analog processing with logic gates, some parameters are essential to the overall behavior of the system. These parameters include the finite slew rate of circuit output signals, the propagation delay of signals, and the exact decision threshold of circuit inputs. You can add blocks from Mixed-Signal Blockset™ to your model to include these effects in time domain simulations of the system.
Blocks
| Slew Rate | Model amplitude, rise and fall times, and propagation delay of logic gates |
| Logic Decision | Threshold crossing detector at input to binary process |
| Operational Amplifier | Model operational amplifier with two or more poles (Since R2021b) |
| Variable Pulse Delay | Delay samples by controlled, continuously variable amount |
| Lowpass Resampler | Convert signal from one sample time to another |
| Linear Circuit Wizard | (Not Recommended) Generate or modify linear circuit |
Functions
