With the increase in signal's bandwidth, the conventional analog to digital converters (ADCs), operating on the basis of Shannon/Nyquist theorem, are forced to work at very high rates leading to low dynamic range and high power consumptions. This paper here tells about one Analog to Information converter developed based on compressive sensing techniques. The high sampling rates, which is the main drawback for ADCs, is being successfully reduced to 4 times lower than the conventional rates. The system is also accompanied with the advantage of low power dissipation.

This paper describes the development of molecular computing in an historical setting. Based on the idea that basic biochemical property of deoxyribonucleic acid (DNA) molecule can be employed to solve Nondeterministic Polynomial Time (NP) problem, several remarkable models and algorithms are proposed for solving complex combinatorial problems. The development is not limited to that; it extends up to the implementation of molecular Boolean Circuits for realization of biological computer. It is concluded that in the past 20 years the DNA research and development made progress on regular base, but the practical line is still lacking behind. The research work in this field is expected to be good in next few decades.

In this paper we present a new technique for demodulating any Shift Keying(aSK) under sampled signal xk using an Orthogonal Decomposer. In this method we generate a phase matching signal xy. Present techniques for demodulation of any Shift Keying signal either require the knowledge of the carrier frequency or need to estimate them. The proposed method aims at detecting phase rate at the boundaries of phase change using xk, with no knowledge of carrier frequency. A sampled version of aSK signal is passed through an Orthogonal Decomposer that estimates and adjusts the phase of the incoming signal and generating a new signal xk phase shifted by π/2, The signal xk is again phase shifted by π/2 resulting xy. Phase transitions are detected using signal ek = xk - xk, for demodulating the aSK signal. This method is a novel way of demodulation focusing on the phase transitions. This will set a new trend in aSK demodulation and leading to a unified technique, spanning ASK, OOKS, BFSK and BPSK with no prior knowledge about the type of modulation.
