Abstract
A signal recording/reproducing apparatus having both bar-type and numeric signal-level displaying units which can be easily read. The apparatus includes a sample-and-hold circuit for sampling and holding an input signal at a first predetermined rate, a first display unit for displaying in bar form the sample values sampled by the sample-and-hold circuit, a data holding circuit for sampling and holding the sample values periodically at a second predetermined rate, and a second display unit for numerically displaying the sample values selected by the data holding circuit. The bar code display can change at a rapid rate to dynamically follow the input signal, while the numeric display changes at a slower rate so as to allow the user sufficient time to comprehend the numerically displayed value.
