Abstract: PURPOSE:To control the frequency characteristic of a reproduced PCM signal (digital sound signal) to be always optimal by recording a recording starting/ stopping signal at a tape while being interlocked with a traveling start and stop at the time of recording, detecting them at the time of reproduction, and updating the frequency characteristic of a transversal filter. CONSTITUTION:The recording start/stop signal is recorded while being interlocked with the traveling start and stop at the time of recording at a recording medium 65. Then, this device is equipped with a start/stop signal detector 78 which detects the recording start/stop signal reproduced from the recording medium 65 at the time reproduction, and outputs an operation start signal, and variable transversal filter 72 whose frequency characteristic is newly updated into the character that can correct the frequency characteristic which is PCM signal inputted from an amplifier 72 has in a recording and reproducing system. Thus, the frequency characteristic of the variable transversal filter 72 can be controlled so that the frequency characteristic of the reproduced PCM signal can be always optimal, even when a consecutive recording due to plural VTR is operated.

Title: Programmable controller, programming tool, and control system and its data transmitting method
Inventor: KAI KOICHI
IPC: G05B19/048
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To realize a transmission load corresponding to the execution load of control and to perform efficient transmission by switching the transmission rate according to congestion information. SOLUTION: A transmission rate switching text is taken out of a text reception part 9 and setting information on the transmission rate included in it is extracted. The transmission speed setting of a transmission controller 1 is changed on the basis of the extracted transmission rate and a transmission speed switching table. Therefore, the transmission controller 11 handles text transmission and reception at the newly set transmission rate from next text transmission. According to whether or not there is congestion and its state, the transmission rate settings are switched synchronously by a programming tool 31 and a programmable controller 32.  Namely, a request to switch the transmission speed is automatically sent to the programming tool 31 according to whether or not congestion is caused to switch the transmission rate, so the transmission load corresponding to the execution load of control can be actualized.
