The ratio of the transmitted pulse width to the compressed pulse width is known as the pulse compression ratio. There are two main types of pulse compression: analog, which uses a linear FM pulse waveform, and digital, which uses a phase-coded pulse waveform....
Other methods such as pulse shaping via digital feedback, predistortion techniques, and feed-forward power supply designs have been evaluated to varying degrees of success. Often these techniques are difficult to implement and the improvement in pulse performance is not worth t...
"pulse waveform". Pulse waveforms are used to represent the transition of a pulse or digital signal or the states of a digital system. In this chapter, we have discussed the concept of logic levels and pulse waveforms. In the next chapter, we will learn about "components of a digital ...
When to Use a PWM The most common use of the PWM is to generate periodic waveforms with adjustable duty cycles. The PWM also provides optimized features for power control, motor control, switching regulators, and lighting control. You can also use the PWM as a clock divider by driving a ...
Request Digital Evaluation Copy Description PWM DC-DC power converter technology underpins many energy conversion systems including renewable energy circuits, active power factor correctors, battery chargers, portable devices and LED drivers. Following the success ofPulse-Width Modulated DC-DC Power Conv...
A Pulse-Width Modulation (PWM) peripheral is used to generate a digital signal with a user-defined period and duty cycle (“ON” time) that can be used to encode a message or control the amount of power supplied to electrical devices. This type of signal can be used...
Second, the digital module acts as a controller of the analog part and simultaneously as a slave for external master controller. This device (Fig. 10(c)) is capable of data acquisition and basic digital signal processing (i.e. averaging). The advantages of the designed device are very low...
