Antennas : Feed Lines : Choke
- Common Mode Choke Theory
- A common mode choke may be used to reduce a type of electrical noise known as common mode noise. Electro-magnetic interference (E.M.I.) in the circuit's environment is one source of electrical noise.

- Remotely-tuned loop antenna for LW and MW
- This article describes how to build a loop antenna for low frequency (LF) and medium wave (MW) reception with remote-controlled tuning. The antenna is extremely sensitive and can be built mostly from parts from old radios and tape recorders. Like all loop antennas, it is highly directional, which allows you to null out unwanted noise sources.

- Local QRM reduction
- It is not always possible to tackle the sources of local QRM. What remains is trying to reduce the noise level by means of your antenna system.

- NFM - noise figure measurement
- NFM (for Noise Figure Meter) is a software application to assist Noise Figure measurement. NFM implements the method of Agilent application notes AN 57-1 and AN 57-2 for noise figure measurement, but with the addition of an adjustable attenuator after the noise source and between the DUT and instrument.

- Qucs - Quite Universal Circuit Simulator
Priority listing
- Qucs, briefly for Quite Universal Circuit Simulator, is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. After that simulation has finished you can view the simulation results on a presentation page or window. Run on Linux.
