Ra is Indian standard whereas Rz is DIN standard
what do you mean by Ra and Rz values
what is Rz and Ra urface finish?
the methodology of measurement and what is measured are quite different. This is critical to understand if you will not be paid for your parts because the Ra you measured is not in fact the Rz surface profile that customer specified.
Approx - Rz is 4 times of Ra

Unipolar NRZ (Non-Return-to-Zero) uses continuous voltage for the entire bit duration, while Unipolar RZ (Return-to-Zero) resets the voltage to zero halfway through the bit duration. This means that Unipolar RZ has more frequent voltage transitions compared to Unipolar NRZ in the time domain.
If z is the midpoint of RT, it means that RZ is equal in length to ZT. Therefore, RZ = ZT. Additionally, the segment RT is twice the length of RZ (or ZT) since Z is the midpoint. Therefore, RT = 2 * RZ.
Because, there are two types of RZ value- shortwave & longwave. A High Longwave RZ value will be less smooth than a high shortwave RZ value, because in shortwave, even though the RZ value is high, the undulations are very close together, and so will appear smooth when measured over a long or short area. A High RZ longwave surface appears less smooth, as the undulations occur over a longer area, and so will have more effect with relation to how smooth the surface is. RZ measures only the height of the surface descrepancy at any given point, its not concerned with the frequency of that descrepancy over any distance of the surface-this is how RZ value can be high, but surface finish appears smooth- Its a High RZ, short wavelength surface.

that's will be depend for the country model Japanese GZ and RZ models have 280hp and 431 tq and the exported GZ and RZ models have 431 hp and around 400 tq
There are no known current NFL RZ codes, but you can get premium to get a lot of gear like pigskin, game ball, and card code.
The choice between Rz (Return-to-Zero) and Pulse Ratio Code (PRC) depends on the specific application and requirements. Rz is simpler and more robust for timing recovery in optical communications, while PRC can offer better bandwidth efficiency and lower average power consumption. Ultimately, the "better" option relies on the context in which they are used, such as the desired data rate, noise tolerance, and system complexity.
