Polar encoding signals, particularly those that utilize long codewords or low signal-to-noise ratios, are prone to synchronization problems. These issues arise due to the presence of noise and interference, which can distort the signal and lead to challenges in accurately detecting the start and end of codewords. Additionally, signals with rapid phase changes can complicate synchronization further, as they may be more susceptible to timing errors. Proper synchronization techniques, such as using preambles or training sequences, can help mitigate these issues.
The digital encoding techniques are of two types--Polar and Bipolar. The polar encoding are--RZ(Return to Zero), NRZ (No RZ) , Manchester and Differential Manchester. Bipolar encoding are--AMI ( Alternate Mark Inversion) and BnZS ( Bipolar n Zero Substitution).

Pulse-position modulation (PPM) encoding type always has a nonzero average amplitude. In PPM, the signal's average amplitude is determined by the positioning of the pulses within the signal. This ensures that there is always a nonzero amplitude level in the signal, even during silent periods.
Due to the melting of polar ice caps, where they live, there habitats are being destroyed and they are ending up in the ocean.
Some problems are easier to solve using polar coordinates, others using Cartesian coordinates.
NO!! It cures them. It is an approved condition in Colordo (Bi-Polar..Anxiety)
Starvation A polar bear faces starvation since the sea ice melts so fast from the earths warming. Then it becomes too hard to hunt seals, a polar bears favorite prey.

They faced problems such as harsh climate, little food, independence, and thin air.
