Fan sizes and speeds impact noise output, with smaller ... and maintains optimal PC temperatures. PWM stands for Pulse Width Modulation, which is a type of signal used to control electronics.

The PWM signal in question is fed through a piezo speaker in parallel with a resistor. The output from the speaker is then sent to an FFT (fast fourier transform) app for Android devices ...

The advantage is the output capacitor gets a kick more often and has less opportunity to droop. You probably want a scope to measure PWM or pulse density, but we’ve talked about how to do it ...

This single-chip, highly integrated active-clamp current-mode PWM controller solution is designed ... high-performance analog and mixed-signal power and protection semiconductors across consumer ...

KTB2140 fully supports the IEEE® 802.3bt 90W specifications and is also compliant with IEEE® 803.2af/at applications. Key applications for the new KTB2140 include Conference Systems, Wireless LAN ...
