Abstract: A signal level displaying apparatus comprises circuits for carrying out time division of input signals of multiple channels, a plurality of level selection circuits having respectively different threshold values and operating to produce outputs in accordance with the levels of the signals thus time divided, and a display part having level electrode parts which are connected respectively to the level selection circuits and disposed on one display screen, and which cause luminescent display to be carried out in accordance with the outputs of the level selection circuits. This signal level display apparatus further has a circuit part for displaying the real time levels of signals and a circuit part for storing and displaying maximum levels.
