Cellugraf signals were used for identifying pages in a book. They were very popular prior to the 1960s and were essentially used in place of placing a paperclip on a page to mark it. In fact, I am looking for Some Graffco Cellugraft Signals for a project I am doing.
Voice signals are analog signals, whereas computer signals are digital .
AGND means Analog ground & DGND means Digital ground. Due to fast switching of digital signals it is possible for noise generation which affect nearby analog signals.(If common gnd used for both analog & digital). If separate gnd used for both the signals.Noise will not affect the signals.

Radiofrequency (RF) Signals: RF signals are used in various wireless communication technologies, including: Cellular networks: Mobile phones use RF signals to communicate with cell towers. Wi-Fi (Wireless Fidelity): Wi-Fi devices, such as smartphones, laptops, and routers, use RF signals to connect to local wireless networks. Bluetooth: Bluetooth-enabled devices, like headphones, speakers, and smartphones, use RF signals for short-range wireless connections. Zigbee: Zigbee is a wireless communication protocol commonly used in smart home devices like smart lights, thermostats, and sensors. NFC (Near Field Communication): NFC technology allows devices to exchange data over very short distances, often used for contactless payments and device pairing. Infrared (IR) Signals: Infrared signals are used for short-range communication between devices that have IR transmitters and receivers. TV remote controls are a common example of devices that use IR signals. GPS Signals: Global Positioning System (GPS) devices receive signals from multiple satellites to determine their precise location and provide navigation information. GPS signals are crucial for location-based services and navigation applications.
neon is used for warning signals
Receptors are proteins on the cell membrane that are used to receive signals
what is the modulation used in telivision for audio signals
They are used to transmit data, TV signals, and telephone signals. They are also used in ovens and radar.
sequence signals are signals that are used to arrange events in proper order...! for example..the teacher is in a wrong grammar..!
Signals from the atom can be used to determine the number and types of atoms present. Amazing!
an encoder is used to convert the binary signals into analog signals. the binary signals are fed to encoder section. then these signals are get converted into its equivalent analog signals. Binary DAC.
As you know a SMPS of a computer converts AC signals to DC signals. Here a capacitor is used to filter AC signals. eNjOy!!
red, redstone dust is used for electric signals.
Smoke signals is a long form of long distance communication. These signals were used in Ancient China and by the Native Americans and Yamanas.
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
pragmatic functions are type of communication signals which are used for certain purpose
