Abstract

PURPOSE: To accurately monitor the correlation between the peak level and frequency distribusion of input signals by effecting the spectral display and the full band display simultaneously at a stop when the level of the full band signals reaches a desired designated level.
CONSTITUTION: The audio signals from an input terminal are fed through narrow band filters 21W2n and a filter 5 to rectifying and smoothening circuits 31W3n and 6 unitl they are fed to a sample hold circuit 4. The spectral signals and the full band signals from the circuit 4 are fed to a multiplexer 7 and fed through a level drive circuit 8 to the level axis display circuit of a display board 9. On the other hand, the signals from a decoder 11 are fed to a frequency drive circuit 10 and further to the frequency axis display circuit of th board 9.
