The data loss is even more severe when I change to a 1G card. The data loss for a 2G card is about one hour without loss, but starts after a long time. There is basically no loss of data when storing
MOS tubes, commonly used semiconductor devices, are widely used in analog circuit design. Here we summarize some common knowledge about discrete MOS tubes. (1) Pin definition For 3-pin packages, the p
I would like to ask if there is a suitable chip that can achieve controllable adjustment of output frequency, specifically: the input is a 0-15V square wave with a duty cycle of 50%. Assuming the inpu
