Abstract: PURPOSE:To save material and cost by connecting an intermediate frequency which is obtained by the conversion of a preamplifier provided near an antenna to a receiver body through a coaxial cable, and sending a local oscillator control signal out of the receiver body through the coaxial cable. CONSTITUTION:The local oscillator VC041 of the mixer 12 of the preamplification part 1 provided near the antenna uses a PLL oscillator, and the intermediate frequency obtained by the conversion of the mixer 12 is connected to the receiver body 2 through the coaxial cable 3.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To surely set the only single recording power with all of information recording and reproducing devices even if these devices vary, to increase the number of erasable times and to improve the reliability of fecording. SOLUTION: Information is test recorded in the patterns consisting of unrecorded parts and recorded parts while the recording power P is successively changed. The test-recorded information is reproduced and the recording signal amplitude m corresponding to the recording power P is monitored. A standardized inclination g (P) is then determined by the equation g(P)=(Δm/m)/(ΔP/P), ΔP: the micro-change rate near P, Δm: the micro-charge rate corresponding to ΔP near m. The optimum recording power is determined and set by evaluating the excess and shortage of the recording power based on g(P).
