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 = 20mV
Use 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.
