Product Description

GCDJ-XH3
SIGNAL, SYSTEM AND DIGITAL SIGNAL PROCESSING TRAINING PLATFORM

System Introduction
GCDJ-XH3 Signal, System and Digital Signal Processing Training Platform
This experimental instrument provides experimental methods for time-domain and frequency-domain signal analysis, and is integrated with digital signal processing functions. With this training box, users can conduct experiments and studies including time-domain analysis of step response and impulse response, simulation of continuous-time systems, analysis and research on sampling theorem and signal reconstruction, transient response of first-order and second-order circuits, state trajectory display of second-order networks, signal spectrum analysis via DSP technology, as well as decomposition and synthesis of signals. It also supports learning and experiments covering the design and implementation of various analog and digital filters.
Adopting the new DSP digital signal processing technology, this training box enables accurate demonstration of experiments such as "signal decomposition and synthesis" and "signal convolution", which are difficult to implement or yield unsatisfactory test results with analog circuits alone, and vividly verifies corresponding theoretical conclusions. Users can systematically understand and compare the performance and characteristics of diverse analog filters (passive & active) and digital filters, and master the design and implementation methods of digital filters.
Equipped with a standard DSP JTAG interface and communication ports for data transmission between the DSP unit and host PC, the training box supports a full range of experiments related to digital signal processing and DSP applications.

System Features

1. Modular Circuit Design

Each experimental unit is divided into independent modules, with module names corresponding to respective experiment titles. Internal circuit diagrams are printed directly on each module, enabling users to quickly grasp circuit structures at a glance.

1. Adopts Advanced DSP Digital Signal Processing Technology

Digital processing accurately demonstrates experiments that are hard to implement or yield suboptimal results with analog circuits, including signal decomposition & synthesis, signal convolution and spectrum analysis. It vividly verifies theoretical derivations and allows comparative evaluation of performance between digital filters and analog filters.

1. Secondary Development Function

Equipped with a DSP digital signal processing unit, PC host communication interface and dedicated secondary development area. Students can complete a wide range of customized experiments, such as designing various digital filters, performing spectrum analysis on analog signals, and conducting convolution calculations.

1. The instrument comes with a built-in digital virtual storage oscilloscope with a 1MS/s sampling rate, supporting real-time sampling of experimental signals.
