Measurments 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 98KHz and 126 KHz of amplitudes 63 mV and 49 mV, of the fundamental show its frequency and ampitude to be? What is the rms value of the fundamental show its frequency and amplitude to be? What are the peak-to-peak amplitude and period od the originating square wave?
