The introduction of the PC with control and data acquisition software opened new doors to the industry. The traditional PLC control-system can now be replaced with a PC control program and a few ADAM modules. This SCADA control system, combined with a radio data link system produced a product with a large market because of its relative low cost, its ease of use and its relative simplicity to install and operate. The combination and integration of specialized software and self manufactured electronic components is very powerful and cost-effective (in this case).
The interface allows you to create control and display objects on the screen. These objects can then be linked together via parameters. Control is established by interfacing the SCADA system with a ADAM control unit that can receive and transmit control signal to other ADAM units up to 5 km apart.
Written in Delphi 5. The product is another Computec initiative. It is sold internationally as a shareware product.
EchoFilter uses the soundcard of a PC to process income audio signals in real-time. The narrow filter bandwidth allow the extraction signals and sounds from the audio signal that may normally be close to inaudible. The real-time spectrum analyzer and spectrogram gives the user an excellent visualization of the audio. The program also includes an automatic gain control, frequency shifting, graphic equalizer, audio compressor and expander, wave file player and recorder and noise reduction filters.
It is intended for radio HAMS, hobbyists, researchers, scientists and students in the DSP field. Uses include weak signal detection, surveillance, audio cleanup, SETI operations, etc.
