摘要:My invention relates to an improved frequency dependent amplitudemodulated translator apparatus and more specifically, to a demodulation apparatuswhich accepts first, or higher, frequency incoming electromagnetic signals of variousaverage levels and produces a second, or lower, frequency output, the rate of whichvaries proportionately in relation to the average first frequency level. The translatoroperates in conjunction with a unique modulation waveform of the first frequency asproduced by a separate exciter apparatus. The waveform consists of a novel signalpattern comprised of a higher first frequency alternating current source of

electromagnetic power which is methodically amplitude modulated in step-like burstswith a plurality of lower, second frequency alternating current rates wherein eachparticular component second frequency rate causes a sequacity of singular firstfrequency bursts of various magnitudes with the absolute step amplitude of each firstfrequency burst being greatest for the less frequently occurring second frequency ratesand least amplitude for the most frequently occurring second frequency rates. Thetranslator recovers the individual component second frequency rates in proportion totheir instantaneous peak amplitude as compared to the overall average signal level and

therefore, when the average signal level is low, the least frequently occurring higherpeak amplitude second frequency bursts will be recovered resulting in a lower secondfrequency output, whereas when the average signal level is higher, the more frequentlyoccurring lower peak amplitude second frequency bursts will be recovered resulting inan accordingly higher second frequency output. The translator is appropriately suited asan indicator of diminishing first frequency electromagnetic field strength between myherewithin disclosed translator and a cooperative exciter, when the coupling between thetwo contrivances is separable in form.
