Digital Oscillograph
Design Introduction The digital storage oscillograph uses a microprocessor for control and data proccesing. It performs a variety of functions that simulation oscillographs cannot, such as leading triggering, combined triggering, burr capture, wave processing, hard-copy export, soft-disk recording, and long-term waveform storage. Typically, the digital storage oscillograph’s bandwidth exceeds 1...
متن کاملNios II-Based Audio-Controlled Digital Oscillograph
With these issues in mind, we designed an audio-controlled digital oscillograph that uses an audio recognition algorithm to control the oscillograph; specifically, it controls the waveform display size attenuation and amplification as well as the scanning speed. The oscillograph display uses a standard VGA interface that can display waveforms on a PC monitor, projector, or other standard output...
متن کاملThe value of high fidelity electrocardiography using the cathode ray oscillograph and an expanded time scale.
The cathode ray is practically free from inertia and therefore an ideal instrumentality for studying variations in electrical potential. A cathode ray oscilloscope with an amplifier system of high frequency response and an expanded time scale, 330 mm. per second, were employed to record electrocardiograms. Such tracings revealed considerable notching, slurring, and other peculiarities not seen ...
متن کاملAn electronic phonocardiograph employing a double-beam cathode-ray oscillograph as the recording device.
A phonocardiograph employing a cathode-ray tube is the theoretical ideal since the natural frequency of the instrument is sufficiently high to avoid distortion of the vibrations to be recorded, the amplitude of the deflections is directly proportional to the movements which excite them, and the cathode-ray beam has minimal inertia and is fully damped. With any of the popular recording devices i...
