1) y(t) = 3e-2tu(t)The function above defines the model of a signal from the braking activities of a vehicle.a)sketch the signal using the information above.b)Determine the power & energy of the signal. 2) A sensor is used to capture voltage signal y(t) from a volcanic eruption & passed through an active highpass filter system for processing.a)Make a circuit diagram sketch for the process.b) Derive an expression for the transfer function of the system. c)Cut-off frequency = 2.5kHz & Input voltage = 20mVUse the above data to determine the values of the circuit components needed to produce an output of five volts. d) Suppose a two volts input voltage is applied to the filter system, In terms of unit step function, i) what is the expression for this input? ii)Determine the output z(t) of the system. Assumption: All the circuit components in the transfer function equation have unity values.
Consider the following continous time signal x(t). Assume that the signal was sampled at a sampling frequency of 20 Hz. Plot the magnitude spectrum of the sampled signal as a function of cyclic frequency. Be sure to include n values of up to +-2. Label x and y axis. Did aliasing occur? If so, what is the aliased frequency? x(t) = 1 + 2cos(2pi25t)

The plot below shows a sampled continuous signal, with red dots indicating sample points. Determine if the signal has been sampled appropriately, so as to avoid aliasing. For the case where the signal has not been sampled appropriately determine the aliased frequency and enter the result in the answer field below (enter a numerical value only +- 5% tolerance). For the case where the signal has been sampled sufficiently enter the sampling frequency. Amplitude 30 20 10 0 -10 -20 -30 0 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.1 Time (seconds)
