Abstract: PROBLEM TO BE SOLVED: To provide a signal generating circuit improved in spurious suppression performance and capable of using a PLL circuit realized with a small capacitance. SOLUTION: A PLL circuit 15 suppresses a spurious component generated by a DDS circuit and a C/A converter 2. An output from a phase comparator 4 of a PLL circuit 15 is distributed into two paths, the one component is used to apply frequency control to a VCO via gain control and the other component is used to apply frequency control to the VCO via a primary filter so as to act a circuit processing the one component like a lead filter and to act a circuit processing the other component like a lag filter. The gain and the time constant of the primary filter are changed depending on color or black/white discrimination to improve the suppression performance and to reduce a capacitance of an integration capacitor C.

Abstract: PURPOSE:To reduce the loss and to increase the current capacity by providing a conductor whose cross section is of T-shape and the width of the upper part of which is selected to be twice or over the width of the base on a dielectric base whose lower face is provided with a ground conductor. CONSTITUTION:The conductor 2 whose cross section is of T-shape and the width of the upper part 2b of which is selected to be twice or over the width of the base 2a is provided on the dielectric base 1 having the ground conductor 3 on its lower face. Since the upper part 2b of the conductor 2 whose cross section is of T shape is surrounded by air (dielectric constant epsilonr=1), the upper part 2b does not almost contribute the impedance and the impedance of the microstrip line depends nearly on the width of the base 2a. Thus, the microstrip line with a high impedance and low loss is easily formed and the cross sectional area is increased, then the current capacity is increased.
