H. Dicke wiU probably lie in the low-frequency part, especially in the selective amplifier of a modulating frequency. This paper deals with the possibility of omitting the selective amplifier. Calculations and experiments show that scarecely any difference in signal to noise ratio can be found with such abbreviation. The stability against temperature and modulating frequency variations,on the other hand,is largely improved by omitting such troublesome circuits. The comparison among several types of low-pass filters,the calculation and measurement of output noise power and the conception of minimum detectable temperature are also discussed.}, pages = {124--131}, title = {糎波太陽雜音受信装置の低周波部における諸問題}, volume = {2}, year = {1952} }
