Measurements taken of a square-wave signal using a frequency-selective voltmeter (called a spectrum analyzer) show its spectrum to contain adjacent components (spectral lines) at 98 kHz and 126 kHz of amplitudes 63 mV and 49 mV, respectively. For this signal, what would direct measurement of the fundamental show its frequency and amplitude to be? What is the rms value of the fundamental? What are the peak-to-peak amplitude and period of the originating square wave?
PASCAL’S WAGER 343 [6–233] Inﬁnity. Nothingness. Our soul has been cast into the body, where it ﬁnds number, time and dimension. It reasons thereupon, and calls it nature, necessity, and can believe nothing else. Unityadded to inﬁnityadds nothing to it, anymore than does one foot added to inﬁnite length. The ﬁnite is annihilated in presence of the inﬁnite, and becomes pure nothingness. So does our mind before God; so does our justice before divine justice. There is not so great a disproportion between human and divine justice as between unityand inﬁnity . The justice of God must be as vast as His mercy. But his justice done upon the reprobate is not so vast as, and should shock us less than, His mercyshown towards the elect. We
