The SDI (Serial Digital Interface) signals used in the Broadcasting Industry and the CCTV Industry have a set of standards that dictate the levels, frequency bandwidth data rate and many other requirements for good data delivery.
The BESSEL NULL FM deviation measurement is an extremely accurate way to obtain a precise deviation setting on any FM modulator operating at any RF frequency. This test requires a Spectrum Analyzer, Sine-Wave Generator, Audio Frequency Counter, and an accurate dBm meter to verify audio
This design process enables designers to build Low Pass Filters that exhibit much higher accuracy than can be done with 10% inductors and 5% capacitors, using only 1% resistors as the required active components. At the same time, inductors created by the FDNR have very
The term dB is used throughout the electronics and communications industries to specify operating levels and equipment specifications. A full understanding of this term and its relationship to levels will help you in your day to day operations.
This is by far the easiest design for a matching impedance pad (either balanced or unbalanced), because it is only necessary to choose the desired voltage reduction ratio and subtract one to determine the factor to be used to compute the remaining resistance values.
A formula is used to determine the RF Bandwidth or occupancy for an FM signal. If you are designing an FM system on microwave or satellite, you will need to take care that your signal does not cross-talk into other signals on the system.
