Abstract: PURPOSE: A second mixer circuit of a double conversion type tuner is provided to prevent the neighboring channel interference and mutual modulation from occurring by preventing signal distortion with the range expanded using a pattern coil and switching device at the second mixer circuit. CONSTITUTION: In the second mixer circuit of a double conversion type tuner, a serial oscillating circuit(100) oscillates the oscillation frequency signal coming from a second voltage control oscillator. A parallel oscillating circuit(200) generates mutual inductance along with the serial oscillating circuit(100) and oscillates the mutual inductance. A bias circuit unit(300) converts the AC signal from the parallel oscillating circuit by compensating the time constant of the AC signal. A switching(400) device turns on responding to the output signal of the bias circuit unit and shifts the level of the first IF signal.

Abstract: PURPOSE: A simulator for packet activity imitation of the Internet in a local area network is provided to perform more actual simulation by performing a system on actual local area network. CONSTITUTION: A pair of packet sorters(11) are inserted into a packet buffer(12) of a packet included in flow to experience arbitrary activity. A plurality of packet buffers(12) adapts arbitrary delay, delay jitter, loss ratio, end-to-end throughput to the packets filtered by the packet sorters. A delay generator(13) calculates, measures, and monitors standby time to be adapted to each packet standing by in the packet buffers based on the delay and delay jitter descriptor transmitted from a capacity modeler(17), and directly transmits the packet exceeding standby time to a packet receiving module. A packet dropper(14) discards the packets within the packet buffers(12) at regular ratio based on the packet loss ratio descriptor transmitted from the capacity modeler(17). A traffic regulator(15) controls the number and the volume of actually transmitted packets per unit time to limit the end-to-end throughput by measuring and monitoring. An activity meter(16) continuously measures and monitors loss ratio, delay, delay jitter, and throughput provided from a simulator for reporting the state and the result to a user.
