Analog Signal Processing

Analog circuits for signal processingAmplification and conversion of weak but clean signals from sensors is no problem. The challenge lies in harnessing the delicate system against environmental influences.

Effects may come from EMC, vibrations or out-band frequencies.
We have experience with various circuits for processing weak signals from a noisy environment, where maximum possible sensitivity, selectivity or dynamic range are necessary.

Besides a substantial circuit-design, PCB-layout, interconnection, and wiring will reduce the influence from sverch external noise-sources.
Out-band frequencies can be rejected with optimized linear filters, without affecting the wanted signals.

 

Some examples of analog circuits:

  • Amplifiers, Multiplexers and Modulators for Cable-TV
  • Radio receivers at crowded ISM-frequencies
  • Filters and Demodulators for Data-acquisition and Telemetry
  • Analog Front-end for RFID, EAS or MD detection-systems
  • Pre-amplifiers, filters and mixers for various inductive sensors
  • Circuits for processing and amplification of high definition audio
