What is an effector? How does signal transduction
result in amplification of a signal? What are some cellular
responses that result from signal transduction pathways?
In an AC to DC rectifier circuit, the output DC signal of the
rectified wave was measured to be
VDC= (6.6±0.6)V and its ripple voltage was measured to
be Vripple=(0.27±0.02) mV. What is the uncertainty on
the quality factor of the rectifier?
Question 6)

signals which relationship exists
between RMS and maximum values? [5 marks]
b) Why AC quantities cannot be added arithmetically as in DC? [5
