Title: Adaptive rounding circuit
Inventor: JIYON ABUTO
IPC: H03H17/02
Filed: 1990-11-07
Abstract: PURPOSE: To generate a dither signal to be added to only the integer part of an input digital signal by combining a dither signal, whose number of bits is equal to the difference between the number of bits of the input digital signal and that of an output digital signal, with the input digital signal to generate the output digital signal. CONSTITUTION: An m-bit input digital signal x(n) is inputted to an adder 12. In this input digital signal, the number of integer bits is (t) and that of decimal bits is (m-t). t integer bits function as a modifier input signal to a dither signal source 14, and this dither signal source 14 outputs an (m-t)-bit dither signal. A frame pulse Fs is inputted to the dither signal source 14, and the dither signal is inputted to a notch filter 16 if the input digital signal is a composite video signal and an arbitrary component of the dither signal generated by a chrominance subcarrier frequency fSC will be filtered. Thus, the dither signal to be added to only the integer part of the input digital signal is generated.

Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To obtain excellent traveling property and durability by forming a magnetic layer on a nonmagnetic supporting body and forming a rugged pattern with specified or larger intervals on the magnetic layer. SOLUTION: A rugged pattern with specified or larger intervals is formed on a magnetic layer by using a surface treating device of a magnetic recording medium. That is, after calendering, a gravure roll is passed over the magnetic layer at specified line pressure to form a rugged pattern (cutoff) with specified intervals on the magnetic layer. The line pressure is controlled to a specified range considering the efficiency so that the gravure roll does not fail to form the effective rugged pattern due to stiffness of a nonmagnetic supporting body. A coating material prepared by dispersing carbon black in a binder is applied and dried on the medium after the surface treatment to form a back coat layer. In this way, a magnetic recording medium having good SN.C/N and satisfactory traveling property and durability is obtained.
