wirelessly connect laptop to smart board
wirelessly connect laptop to smart board.?A typical mobile phone charger uses a flyback circuit topology. The interference waveforms generated by such chargers are complex and vary greatly from charger to charger, depending on circuit details and output voltage control strategies. The variation in the amplitude of the disturbance is also large, depending on the design effort and unit cost of the manufacturer's investment in the switching transformer shield. Typical parameters include: Waveforms: Includes complex pulse width modulated square waves and LC ringing waveforms. Frequency: 40~150kHz under rated load. When the load is very light, the pulse frequency or skip cycle operation drops below 2kHz. Voltage: Up to half of the peak voltage of the power supply = Vrms / ?? 2.
