Mini electronic devices require multiple supply voltages to protect their circuitry. If this  supply voltage are improperly applied, it can resulting distracted process where internal conduction junction become biased, resulting an uncontrolled current flow. There are 4 methods of Power Supply sequencing. There are simultaneous, sequential, ratio metric and offset. We have to chose the method that meets system requirement.

This is EMI Filtering video. This video explained us about EMI Filtering, EMI Filtering Element, and EMI Filtering Leakage Currents. In this video, conducted mode RFI limit is illustrated on the diagram. On that diagram, the RFI has fix bandwidth. It’s claimed 9 KHz wide when scanning from 150KHz to 30MH and turning 20H when scanning below 150KHz. EMI filtering […]

This is how to make crystal radio part two. This video explain how to assemble a crystal radio in ten minutes. This radio utilizes a different material from different manufacture. This radio use the internal part of radio. Then it is connected to the tuning coil. This part is build from the coil and ferrite and also tuner. The antenna […]

Crystal radio is a simple radio receiver that need no power source. It receives power from radio wave. This video shows how to make a crystal radio. This is first part that explains the parts of crystal radio. The parts of the crystal radio are the crystal, crystal earphone, coil, antenna, and earthing wire. The crystal is used to draw […]

This is how to make crystal radio part 3. In this video, a explanation of the variant of crystal radio is shown. This is two part radio. This radio has two wires, they are antenna and earthing wires. And between two of them there is a diode. The diode is used as bridge between that two connection. The earphone is […]
