Digital Burst Transmitter with Remote Control

The Digital Burst Sensor is designed to impact the transmission of audio data through an RF controller.

The system has high protection against detection complexes of radio monitoring indicators and fields and provides high quality sound transmission.

This system is based on the accumulation of audio data into the internal memory of the transmitter and its subsequent transmission in short compressed packets at high speed. The receiver performs the opposite procedure: receives high-speed compressed packets, corrects errors, stitches packets together, and converts them from digital to analog format.

The Main Advantages of Transmission Impulse Data

• The short transmission time is the system of hidden radio monitoring systems for sensing.

• Determining the frequency of field indicators with built-in frequency meters is almost impossible due to the wide frequency range of the signal and the long-term fine-tuning of the frequency meters.

• Almost impossible to capture and change audio data transmission.

• High-quality audio transmission.

• Low power consumption.

Switching on/off the transmitter and changing the operating modes (ADC sampling frequency, duration and repetition period of packages) can be made from the remote control.
