474 Transformer & Amplifier Module

  • 474 modular transformer and amplifier unit
  • 474 transformer unit

Given a signal having both AC and DC components, the 474 transformer allows de-coupling of the two, with the DC being blocked. Gain can then be applied to the sought after AC signal to ensure optimal recovery.

Voltage biasing of the detector used can be achieved by applying voltage across the primary coil of the transformer.
