We carry out an all-inclusive practice in analog electronic circuit for freshman engineer. For example, they design for the analog electronic circuit, manufacture and test of wireless microphone, and produce a technical report in this practice. We concerned that they hardly experience to design and test anything analog electronic circuit in their school days, and they are poor in approach of thinking by themselves when they encounter something new. We investigate whether they have had a chance to experiment and measure to see something, and been interested in making something their hands before joining our company. We find that there is the correlation between experimental experience and understanding of this training.
