| Posted: 31 Jul 2013 12:51 AM PDT In the event of we need to build a variable DC power supply that output of 1A and can adjust up to about 30V. Most people will use LM317 because high-efficiency, easy to apply and cheaper Description It have an adjustable 3-terminal positive voltage regulator designed to supply more than 1.5 A of load current [...]  |
| Simple nonlinear low pass filter Posted: 30 Jul 2013 09:31 AM PDT This is a simple low pass frequency filter circuit on nonlinear passive. We use passive components without transistors and any ICs. So is easy circuit. and It is small size and easy to made for do not used the external power supply, but refuse a lot of noise ripples and need to a input voltage [...]  |
| The CD4049 Hex inverter simple datasheet Posted: 30 Jul 2013 05:09 AM PDT The CD4049 is a CMOS logic chip, that is six independent inverter. It is used for interfacing and to make simple clock pulse generators and oscillators. Connect two in series to make a non-inverting buffer. The input-signal high level (VIH) can exceed the VCC supply voltage when these devices are used for logic-level conversions. These [...]  |
