A signal is applied to the input such that the output increases by 12 dB. The level of the signal needed to produce this is noted. In this case, it was found to be 0.25 microvolts. According to the radio designer, intelligible speech can be detected 12 dB above the receiver's noise floor (noise and distortion).
The serial DCD pin can be used to accurately detect a PPS signal, as described in RFC 2783: [1] One convenient means to provide a PPS signal to a computer system is to connect that signal to a modem-control pin on a serial-line interface to the computer. The Data Carrier Detect (DCD) pin is frequently used for this purpose.
Google Japan has open sourced the "firmware, circuit diagrams, and design drawings" for all of its novelty input devices, beginning with Google Japanese Input Morse version on April 1, 2012, to allow anyone to build their own versions of the devices. [255] On April 1, 2013, Google announced Google+ Emotion.

Since particular machinery problems generate vibration at specific frequencies, machinery faults can be detected or diagnosed. Vibration Spectrum Analyzers use the signal from different types of sensor, such as: accelerometers, velocity transducers and proximity sensors. The uses of a vibration spectrum analyzer in machine condition monitoring ...

Recovering signals at low signal-to-noise ratios requires a strong, clean reference signal with the same frequency as the received signal. This is not the case in many experiments, so the instrument can recover signals buried in the noise only in a limited set of circumstances. Example of a lock-in amplifier
