This intuitive yet rigourous introduction derives the core results of digital communication from first principles. Theory, rather than industry standards, motivates the engineering approaches, and key results are stated with all the required assumptions. The book emphasizes the geometric view, opening with the inner product, the matched filter for its computation, Parseval's theorem, the sampling theorem as an orthonormal expansion, the isometry between passband signals and their baseband representation, and the spectral-efficiency optimality of quadrature amplitude modulation (QAM).

If this was the case, we expect that the importance of household consumption will be underestimated when we use the ownership of animals, bikes and/or motorbikes as instruments.

However, the microfinance sector is still relatively small and weak compared to other global regions and despite the huge potential market.
