Data Transceiver
The device that receives electrical impulses is typically a sensor or a receiver, depending on the context. Sensors are used to detect changes in the environment and convert them into electrical signals. Receivers are used to pick up and process electrical signals transmitted wirelessly or through a wired connection.
The Doppler method uses ultrasound; it involves a handheld listening device that transmits the sounds of the heart rate through a speaker or into an attached ear piece.

An ultrasound probe is a handheld device that emits sound waves and captures the echoes that bounce back from internal organs and tissues. It is used in medical imaging to produce real-time images of the body's structures like organs, muscles, and blood vessels. The probe is moved over the skin's surface to visualize internal structures.

If you are referring to the traditional PSTN phone, the signals that it receives are analog. If you want to know about VOIP phone, it is digital in nature. However, analog can be converted to digital by using a device called ATA.
A satellite radio antenna is typically considered a passive device. It receives signals transmitted from satellites but does not amplify or generate its own signals. The antenna captures the radio waves and sends them to a receiver, which processes the signals for audio output.
