Evaluation and Demonstration Boards and Kits are widely used in research, development, certification, and production of electrical and electronic devices such as microprocessors, FPGAs, ASICs, and PCs. These boards and kits can provide users with a variety of technologies, such as digital signal processing, programmable logic, analog signal processing, and various communications protocols. The DEM-PCM2902 is an example of such a board, providing users with flexible audio processing technology and hardware to help optimise audio signals.

The DEM-PCM2902 consists of three components: an MCU, an audio processor, and a USB module. The MCU is a 32-bit ARM Cortex-M4 processor, capable of performing signal processing such as filtering, effects, and other audio processing tasks, as well as providing USB connectivity. The audio processor is a Microchip PIC32MX processor supplemented with on-board audio components such as a 24-bit digital-to-analog converter, a 24-bit analog-to-digital converter, and a high fidelity fused bi-directional synchronous stereo audio codec. The USB module provides two USB ports for connecting the board to a computer.

The DEM-PCM2902 provides a comprehensive set of software components for users to process audio signals. This includes a serial application programming interface (API) for developing embedded applications, as well as a Windows-based software component package for designing audio applications. The software components allow users to control the board’s audio processing capabilities, and to optimize audio signal processing. This includes the ability to process stereo audio signals, perform time and frequency domain analyses, and provide sound effects such as equalization, compression, reverberation, and delay.

The DEM-PCM2902 is designed to be used in a variety of application fields, such as automotive, consumer electronics, and professional sound systems. In automotive applications, the DEM-PCM2902 can be used to measure and improve the audio performance of car audio systems. In consumer electronics, the board can be used to design and prototype advanced audio systems for home theater systems and high-definition televisions. In professional sound systems, the board can be used to analyze and optimize audio systems for large venues, such as stadiums and concert halls.

The DEM-PCM2902 works by transforming analog input signals into digital signals. It does this using a process called Pulse Code Modulation (PCM). PCM is a form of digital modulation technology, which works by converting an analog signal into a digital signal by sampling the input signal at consistent intervals and encoding the samples into a bitstream. The DEM-PCM2902 board then uses this digital information to process the audio signals to form the desired output signal. This process can be used to add effects, adjust the frequency response, or analyze the signals for diagnostic purposes.

In summary, the DEM-PCM2902 is an example of an Evaluation and Demonstration Boards and Kit. It is designed to provide users with a comprehensive set of components for processing audio signals in a variety of application fields, such as automotive, consumer electronics, and professional sound systems. The board works by converting analog signals into digital signals using Pulse Code Modulation (PCM), and uses this digital information to process the audio signals to form the desired output signal.
