<p>A method for time domain to frequency domain conversion is described. Time-domain input data is obtained. The input data is converted from the time domain to the frequency domain to provide frequency-domain data. Frequency-shifted time-domain data is produced. The frequency shifted time-domain data is converted from the time domain to the frequency domain to provide frequency-shifted frequency-domain data. The frequency-domain data is combined with the frequency-shifted frequency-domain data to produce combined frequency-domain data. The frequency-domain data is provided for further processing by a test and measurement system.</p> |
