| Question | Answer |
| Varies the amplitude or height of a signal to represent the binary data | Amplitude-Shift Keying (ASK) |
| Changes the signal into a carrier signal | A Keying method |
| When noise occurs it normally affects amplitude of the signal meaning this keying method is more susceptible to signal loss | Amplitude-Shift Keying (ASK) |
| Varies the frequency of the signal. | Frequency-Shift Keying (FSK) |
| One frequency can represent the 0 bits and another can represent the 1 bits | Frequency-Shift Keying (FSK) |
| Varies the phase of the signal | Phase-Shift Keying (PSK) |
| A phase change can represent the 0 and no change in phase can represent a 1 | Phase-Shift Keying (PSK) |
