发明名称 Musical instrument tuner
摘要 A musical instrument tuner includes a means for measuring the frequency of a note played on an instrument, a minimal display means, a means for powering and depowering the tuner, and a means for collecting the signal to be measured. The tuner displays sharp and flat indications to the user, eliminating the ambiguous finite width "in-tune" window.
