DTMF

Dual-tone multi-frequency (DTMF) signaling is used for telephone signaling over the line in the voice-frequency band to the call switching center. The version of DTMF used for telephone tone dialing is known by the trademarked term Touch-Tone, and is...

VCO

Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce...

Data Terminal Equipment

Digital delay generators produce pulses at precise, programmed intervals to trigger devices under test. They are also used for gating, timing, triggering, and syncing. Basic digital delay generators are single-channel devices. More complex products with...

TLC 555

TLC 555Most modern energy meter have one or more LEDs which blink at a rate directly related to the energy used. The one above has two of them : one pulses at 1000 pulses per active kWh, the other one pulses at 1000 pulses per reactive kWh. I dealed...
