This circuit generates a two-tone effect very much alike the cuckoo song. It can be used for door-bells or other purposes thanks to a built-in audio amplifier and loudspeaker. Agreeable, very close ...

This rain sound effects generator circuit simulates the rain noise and may be used in the field of electronic music and radio shows. As a noise source we use a germanium diode that is directly ...

A random noise generator is pretty handy when working with music, and building one using a micro-controller can be pretty trivial. So it’s nice when someone comes along and builds it from a few analog ...

The behavior of analog circuits can often be characterized by sweeping their inputs with a signal going across a range of frequencies and then observing the output. These sweeps can be composed of ...

Winbond Electronics announced it has recently begun volume production of a handset-use 16 polyphonic sound generator chip, the W5691, according to company consumer... Save my User ID and Password Some ...

A personal computer (PC) sound card can be the basis for a readily available signal generator for testing electronic circuits. The usefulness of these signal generators is limited, however, because ...
