GATE EC 2011 Question Paper (13-Feb-2011) (Shift 2)

The differential equation $100\frac{d^y}{d{t}^2}-20\frac{dy}{dt}+y=x(t)$ describes a system with an input x(t) and an output y(t). The system, which is initially relaxed, is excited by a unit step input. The output y(t) can be represented by the waveform

For the transfer function G (jω) = 5 + jω, the corresponding Nyquist plot for positive frequency has the form

The trigonometric Fourier series of an even function does not have the

When the output Y in the circuit below is ‘’1’’, it implies that data has

The logic function implemented by the multiplexer circuit is (ground implies a logic “0”)
