Abstract
A discussion is given of the effects of intermodulation in bridge detector amplifiers and the means by which they may be minimized. A figure of merit is defined to assess the performance of an amplifier, and is used to demonstrate the importance of tuning and feedback. The problems associated with the use of amplifiers containing both tuned and untuned stages are discussed, and the arrangement of these stages for minimum intermodulation is derived. The paper includes a description of a practical amplifier for use at 1 and 1.6 kc/s in which the intermodulation is unusually low.
