摘要:
An oscilloscope intensity regulation apparatus is disclosed. The oscilloscope displays wave-forms with the regulated intensity in spite of various wave-form repetition rates or sweep ranges. The scope has a CCD sensor 11 on a CRT 10. The CCD output 28 is applied to a video circuit 12 delivering a video signal 29. The CPU 4 instructs an intensity of an electron beam to a Z-axis circuit 8 and an AGC (automatic gain control) revision signal 27 to a AGC circuit 13 in accordance with an intensity input signal 21. The AGC circuit 13 controls its gain for amplifying a video signal 29 from the CCD 11 via the video circuit 12. When the video signal 29 is small in its amplitude, the AGC circuit 13 has a large gain. When the video signal 29 is large, the circuit 13 has a small gain. Therefore, an intensity of wave-forms being displayed is regulated in the intensity desired, in spite of various repetition rates of the wave-forms or sweep velocities.

A wave-form observation apparatus i.e. a digital oscilloscope configured to store and display wave-forms being displayed by a simple operation is disclosed. The analog input picture signal 1 includes wave-forms, characters and figures with their intensity information. The analog signal 1 is A/D converted to a picture data 2. A subtracted picture data 3 is obtained by subtracting a predetermined value from an intensity of the stored picture data 7. Two intensities of the data 2 and 3 are compared. In a ready state for the memory operation, the predetermined value is set to zero, By pushing a button 16, the picture data 2 having strong intensity is selected in the switch S2 to obtain intense picture data 6. Thereafter the switch S2 selects the data 3 which is equal to the intense picture data 6 in their intensities. Thus the stored picture data 7 is repeatedly displayed in the memory operation.

[Object] To make it possible to control a CEC-non-compliant device connected to a television receiver by using a remote control sender of the television receiver.[Solving Means] The fact that a physical address [2000] is a device (Recording Device) that a photo player 370B controls in place of the physical address [2000] is set by a user in the photo player 370B. In accordance with this setting, the photo player 370B decides a logical address {1} as a CEC-controlled Recording Device. When the user operates a disc recorder 210B that is a CEC-non-compliant device by using a remote control sender 277, a television receiver 250B generates a CEC control command addressed to the disc recorder 210B. The photo player 370B detects the CEC control command, converts the CEC control command into an infrared remote control command, and sends the infrared remote control command from an infrared sending unit 384 to the disc recorder 210B.
