Signal amplification circuit The ultrasonic signal which was received with the reception sensor is amplified by 1000 times(60dB) of voltage with the operational amplifier with two stages. It is 100 times at the first stage (40dB) and 10 times (20dB) at the next stage. As for the dB (decibel)‚ refer to "Logarithm Table". Generally‚ the positive and the negative power supply are used for the operational amplifier. The circuit this time works with the single power supply of +9 V. Therefore‚ for the

spindle attached to the front wheel of the vehicle. The disc has ten equidistant holes on its periphery. On one side of the disc an infrared LED is fixed and on the opposite side of the disc‚ in line with the IR LED‚ a phototransistor is mounted. IC LM324 is wired as a comparator. When a hole appears between the IR LED and phototransistor‚ the phototransistor conducts. Hence the voltage at collector of the phototransistor and in- verting input of LM324 go ‘low’‚ and thus output of LM324 becomes
