This block diagram can be implemented using either analog or ... FM is still used today in applications such as broadcast and land-mobile radio. How do we implement FM using quadrature modulation? In ...

In this fm modulator prototype the varactor bias was 7.5V for the best linearity but this could be different with other varactors. I love all about electronics, circuit diagrams and crazy projects ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the ...
