DSP chips are widely used in digital control and motion control, including disk drive control, engine control, laser printer control, inkjet control, motor control, power system control, robot control, high-precision servo system control, CNC machine tool control, etc.

The main applications for low-power, handheld devices, and wireless terminals include mobile phones, PDAs, GPS, and digital radio stations.

Digital Signal Processing Digital Filter

There are many practical types of digital filters, which can be roughly divided into Finite impulse response type and Infinite impulse response type, and can be realized in hardware and software. In hardware implementation, it is composed of units such as adders and multipliers, which is completely different from analog filters composed of resistors, inductors, and capacitors. Digital signal processing systems are easily made with digital integrated circuits, demonstrating advantages such as small size, high stability, and programmability. Digital filters can also be implemented using software. The software implementation method is to use a universal digital computer to program and perform digital filtering calculations based on the design algorithm of the filter.
