Signal processing deals with the analysis and operation of a. mechanical signals b. electrical signals c. biological signals. These can be b. digital c. analog which vary across a range of values or b. digital with only two possible values.
Explanation:
- In signal processing, a signal is a function that conveys information about a phenomenon. In electronics and telecommunications, it refers to any time varying voltage, current or electromagnetic wave that carries information.
- A signal may also be defined as an observable change in a quality such as quantity...
- A signal can be audio, video, speech, image, sonar and radar-related
- Signal processing deals with the analysis and operation of mechanical signals, electrical signals and biological signals.
- The value of the signal is an electric potential which is voltage is also a signal.
- The term analog signal usually refers to electrical signals. Analog signals may also be other mediums such as mechanical, pneumatic or hydraulic.
- An analog signal signifies a continuous signal that keeps changes with a time period. A digital signal signifies a discrete signal that carries binary data and has discrete values. Analog signals are continuous sine waves. Digital signal is square waves

Answer: Both the server and the client send certificates
Explanation:
In a given network session the server sends a certificate to the client . The client is able to verify that the server's identity, the authentication uses a public encryption key and a digital signature .The client in turn retrieves a private key they can use to create a digital signature . A certificate is then sent by the client across the network to the server and it uses it to authenticate the client's identity . Once the server has confirmed that the client is who they say they are it grants access for the verified identification.
