PURPOSE:To facilitate visual sensation analysis and to display a three- dimensional projection mode, by mounting a signal processing means for processing an input signal containing the same phase and orthogonal components, a display control means and a means for generating the control signal of each marker display. CONSTITUTION:The input signals I, Q from input lines 61, 63 are respectively sampled by samplers 67, 69. A conversion processor 75 inputs I(nt), Q(nt) and TIME(nt) from a timing controller 73 to convert the same to the signals XCRT, YCRT to an XY display apparatus 77. A microprocessor 72 receives the order of an operator from a key pad 74 to control the operation of a processor 75 on the basis of a selected display mode and other parameter and further controls the operation of a digital stroke processor 76 to display a marker and alpha-numeric character on the apparatus 77. The outputs of the processors 76, 75 are multiplexed by a multiplexer 78 to generate a display signal. In a three- dimensional display mode, the processor 75 generates XCRT and YCRT signals for projection chart on the basis of the coordinates triplet of the input signal.
