The signal and system training box provides the experimental means of frequency domain and time domain analysis of the signal, it can be used to analyze step response and impulse response in time domain; analysis and research of signal spectrum, signal decomposition and
synthesis; AM modulation and demodulation, FDM frequency division multiplexing; analysis and research of continuous time system simulation and sampling theorem and signal recovery;
realizes the transient response of first and second order circuits, second-order network state trajectory display, and various filter designs and implementations. The platform is designed in modular form, divided by functional units, and the circuit principle is clear at a glance. System features:
1. Circuit modular design: The experimental units are all divided by modules, and the experimental names correspond to the module names. The circuit inside the module is drawnat the corresponding position, so that the experimenter can see it at a glance.
2. Compact structure, stable and reliable performance; strong expansibility, you can design your own experimental circuit.
3. Optional Proteus simulation software can simulate various functional circuits in the simulation signal system; at the same time, adapt to virtual instruments such as oscilloscope, logic analyzer and signal generator to facilitate the analysis and research of the circuit to improve the comprehensive ability of students.
System composition:
1. Power input module:
Provides +5V/1.0A, -5V/0.5A, +12V/0.5A, -12V/0.5A power output. When equipped with LH-DB power protection board, there is undervoltage, overvoltage , overcurrent and short circuit alarm functions. When a fault occurs, the system power is automatically cut off; after the fault is removed, it is automatically restored.
