Linearization and Analog Signal Processing
R2026bIn 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.
