can we produce cosine wave instead of sine wave? will it
usefull?
Answer Posted / raviteja nowduru
the basic difference between sine and cosine is just 90
degrees phase shift.the fourier transform of sine is cosine
and vice versa.it is easy produce sine wave compared to
other alternating quanitities.that is the reason y all
generators produce sine although they can produce other
altering quantities
