What is the multiplication of two signals?

Multiplication of signals is exploited in the field of analog communication when performing amplitude modulation (AM). In AM, the message signal is multiplied with the carrier signal so as to obtain a modulated signal.

What is the inner product of two signals?

The inner product is a generalisation of dot product in the signal (vector) space. The x(t) and y(t) are said to be orthogonal if their inner product 〈x(t), y(t)〉 = 0, and if each vector is also a unit vector, the vector set is called orthonormal.

How do you add two signals together?

The sum of two continuous time signals 𝑥₁(𝑡) and 𝑥₂(𝑡) can be obtained by adding their values at every instant of time. Likewise, the difference of two continuous time signals 𝑥₁(𝑡) and 𝑥₂(𝑡) can be obtained by subtracting the values of one signal (say 𝑥₂(𝑡)) from another signal (say 𝑥₁(𝑡)) at every instant of time.

Can we add two signals?

Signal addition—Two signals x(t) and y(t) are added to obtain their sum z(t). An adder is used. Constant multiplication—A signal x(t) is multiplied by a constant α. A constant multiplier is used.
