E2.3 Given a two-input neuron with the following weight matrix and input vector:
w=[32] and p = [-5 7], we would like to have an output of 0.5. Do you
suppose that there is a combination of bias and transfer function that might allow
this?
i. Is there a transfer function from Table 2.1 that will do the job if the bias is zero?
ii. Is there a bias that will do the job if the linear transfer function is used? If yes,
what is it?
iii. Is there a bias that will do the job if a log-sigmoid transfer function is used?
Again, if yes, what is it?
iv. Is there a bias that will do the job if a symmetrical hard limit transfer function is
used? Again, if yes, what is it?
E2.2 Consider a single-input neuron with a bias. We would like the output to be -1
for inputs less than 3 and +1 for inputs greater than or equal to 3.
i. What kind of a transfer function is required?
ii. What bias would you suggest? Is your bias in any way related to the input
weight? If yes, how?
iii. Summarize your network by naming the transfer function and stating the bias
and the weight. Draw a diagram of the network.
E2.1 A single input neuron has a weight of 1.3 and a bias of 3.0. What possible
kinds of transfer functions, from Table 2.1, could this neuron have, if its output is
given below. In each case, give the value of the input that would produce these
outputs.
i. 1.6
ii. 1.0
iii. 0.9963
iv. -1.0

- Q2. The slew rate of an amplifier can cause signal distortion at its output if wrongly chosen. State the criterion for selecting the slew rate of an amplifier to avoid signal distortion. A step signal of 5 mV is applied to an inverting amplifier shown in Figure 2, which has a slew rate of 0.05 V/us. Estimate the time required for the output voltage of the amplifier to reach within 10% of its final value. If the input to Figure 2 is a sinusoidal signal of 0.02 sin(2πft) V, determine the maximum frequency that can be applied to the circuit without causing signal distortion due to the limitation of its slew rate (0.05 V/µs). In order to minimise the output offset voltage of Figure 2, a compensating resistor should be added to Figure 2. Draw a modified circuit diagram that includes the compensating resistor.
