2 test site for normal indoor lighting, tracking system A is not correct for the direct sunlight and strong light source; 3 metering system components should be included in the source tracking system A; 4 source tracking system to track a point source in the process of finding , with no human intervention in light tracking systems; 5Laser key: when press this key, the head of  cell phone jammer would emits red laser beam. In addition to play a part (3) items, the point source of current shall be 300 ± 15 mA; 6. during the play portion (3) of the test shall not change the light source tracking system parameters or the circuit mode; four scoring system solution project design report theoretical analysis and calculation of the test circuit and program design and test results of the program structure and regulatory design report completed Subtotal (1) of the basic requirements to complete the first (2 ) of the complete article (3) Sub-total completion of the first (1) of the complete article (2) play a part of the completion of the first (3) Other Subtotal Total scores 2,898,330,102,020,501,515 15 5 50 130 A-4 National Undergraduate Electronic Design Contest 2010 TI Cup Invitational analog electronic systems feature experimental questions waveform synthesis circuit (signal waveform synthesis experimental circuit (C items) experimental circuit for the task to design a circuit that can produce many different frequency of the sinusoidal signal, and these signals are then synthesized to approximate the square wave signal and the circuit diagram shown in Figure 1: Page up key: press this key on  cell phone jammer once, the file would turn one page up; press it for a long time, the file would turn up constantly and rapidly.Schematic diagram of two circuit in Figure 1, requires 1 basic requirements (1) square wave oscillator signal by the sub- frequency and the filtering process, while producing a frequency of 10kHz and 30kHz sine wave signal, both signals should be defined phase relationship; (2) produces no significant distortion of the signal waveform, peak amplitude, respectively 6V and 2V; (3 ) produced by a phase shifter and adder circuit consisting of signal synthesis, will produce the 10kHz and 30kHz sine wave signal, as the fundamental and 3rd harmonic, an approximate square wave synthesis, the waveform amplitude of 5V, the shape of the waveform synthesis Figure 2 Figure 2 using the fundamental and harmonic synthesis of approximately 3 square wave (2) play a part (1) re-50kHz sinusoidal signal generated harmonics as a 5, involved in signal synthesis, the synthetic waveform is more close to the square wave; Page down key: press the key on the body of  cell phone jammer once, the demonstrating file would turn one page down; press it for a long time, the file would turn down constantly and rapidly.A-5 (2) The composition according to the triangular wave harmonic relationship, the design of a new signal synthesis circuit, will produce the 10kHz, 30kHz and other sinusoidal signals, a similar synthesis of the triangular waveform; (3) Design a sinusoidal signal to the amplitude of each measurement and digital display of the circuit, the measurement error of less than ± 5%; (4) other.
