This document summarizes the results of experiments on a linear system simulator. It examines the open-loop response to step inputs for different components, including an error detection variable gain amplifier with a gain of 15.2, an uncommitted amplifier with gains of 1 and 10, and an integrator. It also examines the closed-loop response of first, second, and third order systems. Key results presented include the output voltages and gains for different inputs and components, as well as the time constant of 1.2ms for one component.
EEP301: linear system simulator
- 1. Experiment LINEAR SYSTEM SIMULATOR Aim:To analyse the effect step input on a linear system (of various order) due to various controls. Introduction: Observations and remarks: OPEN LOOP RESPONSE Error detection cum variable gain: With an input of 100mv, we get 1.52V i.e. gain is 15.2. Fig. 1 Uncommitted Amplifier: For a square wave of 1V pk-pk an output of 4.4V is obtained with gain 1 and for gain of 10 an output of 15.6V is obtained, with inverted signal.
- 2. Fig 2 For gain=1 Integrator: The output for voltage is 1.08V with an input of .1 V (note that the fig is with 10x probe). Fig 3 Time constant: Time constant, ∆T=1.2ms (time to rise to 63.2%)
