They may appear compressed on your browser due to differences in video mode, but each would exactly fill the Daqarta screen. In particular, the trace grid may appear faint, especially in 16-color mode. Each of the links below takes you to a page with one or two screen images plus descriptive text. Image size ranges from 10 Kbytes to 32 Kbytes each. Speech spectrogram acquired with SB16.
Image shows individual syllables, glottal pulse harmonics, etc.
LPTX SAR model ADC performance. Images show waveform and spectrum of 540 Hz sine input. Synchronous sampling vs windowing. One image compares spectra of signals sampled synchronously vs. asynchronously, while another compares unwindowed vs. Hanning window effects on the asynchronous spectrum. Waveform averaging recovers sine wave buried in noise.
