PPM- Parts Per Million I'm not aware of PWM
the pwm output can be converter to ppm by passing pwm through a monostable multivibrator with a low stable state and high quasi stable state and which is negative edge triggered.
PWM is Pulse Width Modulation. It is a Digital control is used to create a square wave, a signal switched between on and off.
PWM stands for Pulse Width Modulation. It is a technique used in electronics to encode information in a pulsing signal. In PWM, the duration of a pulse in a waveform is varied to convey information. This method is commonly used to control the power delivered to electrical devices, such as motors, LEDs, and other components, by adjusting the average power over time.
Portland International Jetport is designated PWM by the IATA for Portland Westbrook Municipal.
Stepped wave Inverter is simple but has lower order harmonics which cannot be eliminated by filters.These harmonics can be eliminated by the Space Vector PWM technique. In the space vector PWM technique, there is 15% increment in maximum voltage compared to PWM, hence Space Vector enables efficient use of DC voltage.Space Vector Modulation provides excellent output performance, optimized efficiency and high reliability compared to similar Inverters with conventional PWM
Obviously by feedback
4 pin header = ability to use PWM fan = automatically adjust fan speed based on whatever variable (typically temperature) 3 pin header = full speed by default non-PWN fan = can control by means of software or fan controller
PWM normally stands for private wealth management. Private wealth management is just a fancy work for brokerage house. It is an economic term used in dealing with financial planning or investments.
Here are a few areas where L298 is preferred: L298 is basically used where H- BRIDGE is required. Where a high power motor driver is required. In the market, there are H-bridges like L293 which are used for the low powered application while L298 is specially designed for the high power applications. Where current control and PWM operable single-chip device is needed. The chip is preferred when control unit can only provide TTL output Also, the chip does not need any additional components to be installed for operating.

harmonics reduced due to multi switching and output is approximately sine wave so filter design and cost reduced.DC link voltage is also reduced because of splitted source.
