What do you get when you combine a direct digital synthesis (DDS) chip, a power detector, and an Arduino ... low pass filter processes the DDS signal and then feeds a two-transistor amplifier.

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for ... pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing ...

Presented below is a simple and cheap 433-Mz RF Sniffer ideal for testing/reverse-engineering most 433-MHz wireless devices. As you can see, the setup is on the Arduino ground with ... of the waveform ...

Arduino has taken the product ... likely be further improved by reducing the signal level via Rset. The 50 Ω output simplifies wideband connections using coax cable and is also compatible with ...

Spectrum Control's family of software-definable, RF+ sysetm blocks work with mixed-signal devices like Direct RF FPGAs (see ...

The detector uses the ANADIGM field programmable analog array (FPAA), which is an attractive alternative for typically used detecting equipment—a PC computer with dedicated software. We implement an ...
