What is difference between direct and indirect generation of FM wave?

Indirect FM generation first produces a narrow-band (relatively low bandwidth/frequency) FM wave, often created using an integrator, a signal multiplier, a phase shifter, and a summer. Then, it multiplies and mixes this wave's frequency properties to achieve the desired frequency deviation and carrier frequency.Direct FM generation uses a voltage-controlled oscillator (VCO) to generate the wide-band FM signal directly. The VCO often consists of an oscillator with a variable capacitance or inductance that allows the resonant frequency to vary with the applied voltage.Direct FM generation has poor frequency stability, so it requires feedback to stabilize this, which complicates the system. Indirect FM generation has good frequency stability, but is noisier since the noise is multiplied during the frequency multiplication.Choosing one over the other depends on what components are available and how the importance of system/signal characteristics is weighted.


Is a side split harder than a middle split?

A side split is a middle split! However, assuming that you mean a left/right split, middle splits are usually more difficult to achieve. It does vary from person to person though!


Why are collisions between the nuclei difficult to achieve?

Atomic nuclei usually have a positive charge, so they will tend to repel each other. A neutron on the other hand, carries no charge and may easily interact with either the electron shells, or with the nucleus.


What is the frequecy of a wave?

The resonant frequency depends on the mass and bulk modulus of water and also varies with pressure and slightly with temperature. It is possible to split water by a frequention that lies around 42 Kilohertz. The frequency is never exactly right because you would need 100% pure water to achieve the theoretical frequency. Even distilled water contains a lot of impurities and is not just pure H2O. The splitting of water was purportedly invented by Stanley Meyer who claimed that electrolysis at 42KHz split water into hydrogen and oxygen using less energy than was released when the two elements were combusted back into a water vapour. The claims were never proven and his work was widely discredited among the scientific community. To date there have been no peer reviews of his work and the experiments have not been repeated. Meyer died in 1998. Although an autopsy showed death by natural causes, some say he was killed to prevent his technology being further developed. Meyer's work will be the subject of debate for many years to come but 12 years after his death, his claims have still not been proven.
