Balun bandpass filters represent a critical advancement in radio frequency (RF) circuit design, integrating the dual functions of balanced-to-unbalanced conversion and frequency selection. These ...
When almost any electronic system passes a certain level of complexity, it requires some sort of filtering—often several types. However, many designers with a predominantly digital background may ...
Most hobbyists use crystals as an external clock signal for a microcontroller. A less common use would be to make a bandpass filter (BPF) for an RF signal. [Dan Watson] explains his crystal ladder ...
A Simple Method of Designing Multiple Order All Pole Bandpass Filters by Cascading 2nd Order Section
Filter design, be it active, passive, or switched capacitor, is traditionally a mathematically intensive pursuit. There are many architectures and design methods to choose from. Two methods of high ...
