2. A solid is rigid and cannot be compressed easily. Reason: Molecules are closely spaced and the intermolecular separation is very small which cannot be reduced further. 3. A solid does not diffuse into another solid easily. Reason: Intermolecular force of attraction is very strong. 4. A solid does not flow and can be stored in a container. Reason: Intermolecular fore of attraction is so strong that molecules do not flow and leave the surface of the solid. 5. A solid on hating usually changes into its liquid state.
To PWM, or not to PWM, That is the Question. Pulse width modulation (PWM) is a fancy term for describing a type of digital signal. Pulse width modulation is used in a variety of applications including sophisticated control circuitry. A common way we use them here at SparkFun is to control dimming of RGB LEDs or to control the direction of a servo motor.
Digital signal processing (DSP) is the numerical manipulation of signals, usually with the intention to measure, filter, produce or compress continuous analog signals.ven if that whole sequence is more complex than analog processing and has a discrete value range, the application of computational power to signal processing allows for many advantages over analog processing in many applications, such as error detection and correction in transmission as well as data compression.
