Reseña del libro "Wireless FM Bug: FM Transmitter But for Baby Monitoring (en Inglés)"
This book is for anybody wanting to make a wireless monitoring or surveillance device. It is very detailed research and knowledge to bless anyone who reads it. It is actually a thesis. The wireless FM bug is a sensitive miniature very high FM wireless microphone transmitter of thetype "Wide Band Frequency Modulation Wireless Microphone (WBFMWM)". Basically, it servesas a detective device to secretly monitor conversation and can be used to detect lies. It can beconsidered as a surveillance device. This is a hardware project which involves RF (radiofrequency) circuit design. What makes the FM bug different from other devices is its wirelessproperty. The FM bug receives sound waves preferably human voice through the microphone. The sound wave is converted into electrical energy and then back to audio signal at the output end. In view of that, there are three (3) stages (modules) involved in the implementation of the bug. They are the audio amplifier, FM oscillator and the RF buffer amplifier stages. The sound wavereceived through the microphone is amplified to a level that can be modulated over RF. The electromagnetic wave that is constantly generated at the FM oscillator stage is buffered with adequate power being supplied to be transmitted strongly through the antenna. Finally, the audio signal is output and retrieved from a broadcast radio FM. Purchase this book to find out more. This is a fantastic book on making a monitoring device.
