AVT5159 B

We present the project of a development board with a complete DSP system included in one integrated circuit. This system has a memory of audio effects that can be created using a dedicated assembler. FV-1 (integrated circuit from NS) is basically a complete microprocessor system for signal processing with the possibility of its processing. The structure includes integrated, among others ADC and DAC converters, program memory, potentiometric inputs for real-time parameter adjustment, RAM memory, reset circuit after power on. The system supplemented with additional external elements (control microprocessor, memory power supply, etc.) allows for a series of interesting 'experiments' with sound.

The device is especially recommended for audio lovers who like experiments with sound

Selected parameters:

• eight predefined sound effects
• input impedance 80-120kom
• output impedance 50-200om
• maximum level of input and output signal - 3Vpp
• harmonic distortion 0.03%
• S / N 93dB
• alphanumeric LCD display
• four buttons for direct processor control
• three potentiometers for adjusting the settings in real time
• communication with a PC via the RS232 interface
• power supply -9Vdc
• in the set there is a printed circuit board, programmed layout, set of elements and documentation
