"Using a direct sequence spread spectrum (DSSS) technique spreads a narrow band channel so that it occupies greater frequency spectrum. By doing this, the signal has greater immunity from narrow band noise."a) Trueb) False

The answer is true

Explanation:

The main reason why a spread spectrum technique is useful is, because it helps prevent interference of any kind . It helps the signal to travel freely without getting jammed.

These signals transmit or travel at low power density and their signals are widespread. The speed spectrum technology is mainly used in bluetooth, and wireless lan etc.

Direct sequence spread spectrum is one of the four techniques of speed spectrum.

The other techniques are frequency hopping spread spectrum. chirp spread spectrum and time hopping spread spectrum.
