Title: Frequency characteristic compensator for ofdm
Inventor: SUGA TAKU
IPC: H04L25/02
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To facilitate adjustment and also to adaptively compensate transmission line characteristics, without performing demodulation by a FET. SOLUTION: Frequency characteristics in a transmission line and a device are detected by using a condition that amplitude is constant in a transmission band, while paying attention to a fact that the signal spectrum of an OFDM signal is flat in the band. That is, for the OFDM signal, the frequency at which frequency ripples take place or the frequency band where attenuation is caused is discriminated, by checking the frequency characteristics. Therefore, a frequency characteristic detection circuit 14 finds the amplitude level of an OFDM signal frequency band, a compensation quantity computing element 15 finds a frequency and a frequency region where the amplitude level drops, and a compensator managing the corresponding frequency band of a compensation circuit 12 is controlled, to compensate for the disturbance of the frequency characteristics in the transmission line or the device.

Title: Television receiver
Inventor: OHIRA SHIZUO
IPC: H04N5/50
Filed: 1993-10-14
Abstract: PURPOSE:To improve operability by facilitating tuning setting between broadcasting stations with adjacent transmission frequencies, by changing the color of a display part corresponding to '0' according to a frequency adjusted value is this '0' or not. CONSTITUTION:A color change part 7 judges whether the adjusted value set at a frequency adjusted value varying part 3 is '0' or not and when that value is '0', a frequency adjusted value display part 4 is controlled so that a display part cursor (1) corresponding to this '0' can be displayed in any color different from that of a bar (2). When that value is not '0', the cursor (1) and the bar (2) are displayed in the same color. Thus, even when the desired tuning frequency to be newly set is adjacent to the previously set tuning frequency and that frequency adjusted value is within a range where the cursor (1) corresponding to '0' is not moved, it can be easily recognized whether the broadcasting received at present is broadcasting at the desired tuning frequency to be newly set or not. Therefore, even when the frequencies are adjacent, the tuning frequency can be easily set.
