Advantages of wireless technology
Wireless communications offer several cost and connectivity benefits for organizations. The rapid rise of remote work – fuelled in part by the pandemic that began in 2020 – has created an environment where employees demand high-performance access to network resources regardless of where they might be.
Wireless networks can be less expensive to build and maintain since they require fewer switches and other components required by wired infrastructures. New wireless standards – especially among them multiuser, multiple input and multiple output – enable physical Access Points (APs) to serve a greater number of users, further reducing costs.
Wireless technologies also support novel services, among them location tracking, Internet of Things (IoT) deployments and remote diagnostics. Finally, advances in wireless performance enable organizations to stress mobility as a primary benefit, thus helping them redefine how they design their offices and workgroups.

Considere o circuito da figura a seguir em que o amplificador operacional é ideal.
Assinale a alternativa em que se apresenta corretamente o tipo de função de transferência implementada por este circuito e o seu ganho em DC, ou seja, no limite de baixas frequências.
A transformada discreta de Fourier (TFD) é das mais
importantes ferramentas do processamento digital de
sinais, estando no núcleo de diversos algoritmos de codificação de áudio, imagens e vídeo. Para uma sequência x[n] de N amostras, a TFD X[k] é definida como 
Considere a sequência x[n] = {1,0,0,1}, 0 ≤ n ≤ 3. Então sua TFD X[k] no mesmo intervalo é
