Abstract : The tests of Device 8-I, serial No. 1 show the amount of frequency distortion to be extremely low. Almost flat response was obtained over the entire frequency limit of the audio oscillator. However, in the case of Device 8-I, serial No. 13, the response at moderate output level was so poor as to render the unit partially ineffective. Reasons for this poor response were centralized in the input stage. (Author)
