The level of accuracy of the proposed system should be
increased for precision works. Moreover, during the
development of this device certain problems were
encountered. One of them was the generation of waveforms
other than the sine wave. An attempt was made to generate a
fundamental plus third harmonic wave but when viewed
through the oscilloscope it was completely distorted. Also
no means have been made to make DC measurements
possible. Hence, study of step responses of various systems
is not possible. There is a possibility of using this scheme
for systems other than electrical through suitable
transducers. This device operates using analog signals
which have a low noise tolerance. An algorithm for sending
digital signals through the soundcard may make this device
