MATLAB library for controlling a Velleman PCSGU250 scope and generator
% Creates two simple arbitrary waveform library files. The first is a
% sinosoidal AM signal. The signal frequency is equal to the PCSGU250's
% frequency setting; the carrier frequency is 20 times that. The second
% function is a sine wave with Gaussian noise added to simulate a noisy
% communication channel. The frequncy of this signal will be equal to the
% PCSGU250's frequency setting.
% Calling this script will calculate each waveform, plot it, and create the
% library file. Press any key to move on to the next waveform.
% The two lib files will be called 'AMWave' and 'Noisy Sine', respectively.
% Use pclab.FgenLibFile to set the lib file using these names exactly.
