DVMEGA AMBE3000 shield fits on top of an Arduino MEGA. This board is equiped with a AMBE3000Vocoder and PCM3500 Codec. The PCM3500 converts the analog microphone signal into a digitalstream (PCM). And that, conversely, the digital PCM stream is converted back into an analog audio signal. The digital PCM format is 8Khz with a depth of 16 bits. This would be an amount of data of128000 bits per second. Not suitable to be sent via a 4800 bps radio connection. The AMBE3000Vocoder makes of 128000 bps a digital signal of 3600 bps. This is the voice information and errorcorrection codes. These error correction codes make it possible to restore a signal which arrives corrupted at the receiver station up to a certain level. DVMEGA AMBE3000 can be used as AMBE Dongle (Digital Voice converter) but also as a digital transceiver in combination with the Dual band radio shield or GMSK shield. |

The DVMEGA AMBE3000 shield will be delivered in conjunction with a LF amplifier / connection board. This board is equipped with a 0.3 watt LF amplifier and connectors for Mike, Speaker and power. Later, this module can be placed on the transceiver mainboard. | |||||||||||||
