  • Program Designs Tee Attenuator To Minimize Stress

    By Frank N. Vitalijic, May 27, 2002

    Symmetrical Tee attenuators are designed on an image-impedance basis with RO ohms as the matching resistance. The figure(a) shows the attenuator for RA = RB, power input...

  • C++ Platform Program Offers Versatile Waveform Spectral Analysis Tool

    By Frank N. Vitalijic, December 17, 2001

    This idea presents a C++ program that uses the complex class, which enables complex arithmetic. The Discrete Fourier Transform (DFT) is applied to the waveform stored in a disk file—a real sequence of double-precision floating-point binary...

  • Program Converts Real Sequences To Cosine Series

    By Frank N. Vitalijic, June 18, 2001

    This program converts a sampled real sequence stored in a disk file to a harmonically related set of cosine waveforms To view the program, click Download the Code at the top of the page.. The cosine series can be used for waveform...

  • Design Method Allows Tradeoffs In Anti-Aliasing Filter Design

    By Frank N. Vitalijic, March 05, 2001

    This idea details a design method for making anti-aliasing prefilter parameter tradeoffs between several factors. These factors include the filter pass-band magnitude accuracy, the filter order (the number of poles), the ratio of sample frequency to...
