The Gould DC Amplifier Plug-in, Model 57-1440-006158, is a pressure transducer and signal conditioner. Several advantages of using this type of amplifier, include:
- Simple circuit arrangement with minimum number of components.
- Can be used to amplify zero and low frequency signals.
- Provides uniform frequency response up to a high frequency.
- Lower cut-off frequency is zero and upper cut-off frequency is determined by values of components used.
