Title: Address mark detection circuit
Inventor: ISHII OSAMU
IPC: G11B27/10
Filed: 1978-11-06
Abstract: PURPOSE: To detect accurately an address mark when a noise arrives in an erasing part by provided circuits, which detects a non-signal part of a string of data of a magnetic disk and that which erases noises form the string of data.  
     CONSTITUTION: Input signal 1 has noises in its address mark part. Output 7 of voltage comparator 3 is digitized with noises contained and then inputted to pulse- interval detection circuit 8. Then NOT circuit 10 outputs output 4 that the number pulse of input 7 is NOTed from the rise of input signal 9, indicating the complete erasing of noise pulses. Therefore, an address mark detection signal is detected accurately. In this constitution, even when noises arrive in the erasing part, an address mark is detected accurately and reliability of an address mark detector can greatly be improved.

Title: De-emphasis circuit
Inventor: NORITA KAZUYUKI
IPC: H04B1/62
Filed: 1986-06-12
Abstract: PURPOSE:To uniform the frequency characteristic by using a control microcomputer so as to discriminate a sub code of a compact disk detected by a digital signal processing unit and giving a de-emphasis coefficient to the processing unit. CONSTITUTION:In the compact disk CD mode, when a sub code input from a digital signal processing unit DSP 10 exists, a sub code of channel Q is fetched. For example, the playing time is displayed on a display device 7 to discriminate a control section of the Q code. Then the coefficient in response to the presence of a pre-emphasis is outputted to the unit DSP 10. The de- emphasis circuit in the unit DSP 10 is in common use for the tuners 1, 2 as the sound source. Thus, a CPU 4 discriminates the mode and transfers a filter coefficient in response to the mode to the unit DSP 10. Thus, since the de- emphasis circuit for the CD player is constituted in the unit DSP 10, the characteristic is uniformed.
