Physicist Davide Bossini from the University of Konstanz has recently demonstrated how to change the frequency of the ...

A software-defined radio (SDR) uses a general-purpose computer processor to perform aspects of digital signal processing in place of analog circuit hardware. This allows for greater flexibility in ...

VARIABLE condensers are now so commonly employed in radio receivers to tune circuits including a constant inductance that the use, some years ago, of variable inductances or variometers with fixed ...

Since the derivation of the Wien network by Physicist Max Wien (prior work was the ballistic bridge by J. C. Maxwell) in 1891, this network has been used in many oscillators’ designs. One of the most ...

An understanding of tuning and autotuning helps designers better evaluate servosystems and judge which motion components best suit particular applications. Servosystems are well known for their ...
