(a) Analog. The output of a pressure gauge is proportional to the pressure
being measured and can assume any value in the given range.
(b) Digital. An electric pulse is produced for every person entering the exhibition
using a photoelectric device. These pulses are counted using a digital
circuit.
© Analog. The reading of the thermometer is proportional to the temperature
being measured and can assume any value in the given range.
(d) Digital. Inputs are given with the help of switches, which are converted
into digital signals 1 and 0 corresponding to the switch in the ON or OFF
position. These signals are processed using digital circuits and the results
are displayed using digital display devices.
(e) Analog. It receives modulated signals which are analog in nature. These
signals are processed by analog circuits and the output is again in the
analog form.
(f) Digital. It has only two possible positions (states), ON and OFF.
(g) Digital. An electric pulse is produced for every vote cast by pressing of
switch of a candidate. The pulses thus produced for each candidate are
counted separately and also the total number of votes polled are counted.
