Signal flow diagram

Signal flow diagram 1:
Block diagram of EL3356-0010

The EL3356 processes the data in the following order

  1. Hardware low-pass 10 KHz
  2. 2-channel simultaneous sampling at 10.5/105.5 kSps with 64-fold oversampling by delta-sigma (ΔΣ) converter and internal prefiltration
  3. 4-fold averager (can be deactivated)
  4. Software filter (can be deactivated)
  5. Calculating the weight

Measurement principle of delta-sigma (ΔΣ) converter

The measurement principle employed in the EL3356, with real sampling in the MHz range, shifts aliasing effects into a very high frequency range, so that normally no such effects are to be expected in the kHz range.
