A1: a) Representation of signal in time and frequency domain, observing the effect of sampling frequency. b) Transmission and reconstruction of an image using BPSK, QPSK and 16-QAM. Plotted the ...

The deployment of low earth orbits is seen as a promising way of enlarging data capacities as well as high data rates. Catering to these interests, optical communication presents possible ways of ...

Sampling from Gibbs distri-butions under continuous, often nonconvex, potentials is a fundamental challenge, which hinders classical methods such as the Langevin dynamics. Existing quantum approaches ...

Conventional sampling focuses on encoding and decoding bandlimited signals by recording signal amplitudes at known time points. Alternately, sampling can be approached using biologically-inspired ...

Back in 2015, the surprise hit of the popular-science world was a slender volume with the English title Seven Brief Lessons on Physics. Written by the Italian-born theorist Carlo Rovelli, and intended ...
