Plotfft

Summary: PLOTFFT is a software program designed for the PDP-12 computer to visualize and process spectral data generated by the CFFT (Continuous Fast Fourier Transform) program. It reads double-precision spectral values from LINCtape, displays them on the system scope, and allows users to adjust amplitude, plot the results on a digital plotter, or write single-precision values to a secondary LINCtape. The program supports both an interactive non-automatic mode for manual inspection and scaling, and an automatic mode for batch processing of specified data blocks.
