This memorandum describes briefly the laboratory tests conducted to determine the signal processing gain of the present Lorad signal processing equipment reference Lorad block diagram, March 1961. These tests were by no means comprehensive or exhaustive, but did suffice to demonstrate the processing gain of the system for several independent but similar setups for mixing and measuring input signal and noise. The numerical results obtained from these tests are sufficient to answer some of the initial questions which were raised concerning the signal processing gain of the system and to determine what losses, if any, could be attributed to particular portions of the circuitry included in the tests. This memorandum should not be construed as a report, as its basic function is to provide, for engineering purposes, information associated with the initial Lorad signal processing analyses. This memorandum covers a portion of the work done under AS 02101-5, S-F001 03 02, Task 8016 NEL El-3 by Code 2633c. Author
