| <Signal flow diagram> |
|
| Digital PCM signal inputted from amp |
|
| Goes through PWM modulator to change signal |
|
| to pulse -> power amplifies small PWM signal to |
|
| large signal in MOSFET -> Through LPF, analog |
|
| signal restored -> speaker output |
|
| <Strengths of digital AMP> |
|
1. High efficiency : Analog amp (50~70%)
whereas digital amp (90%) |
|
2. High output : Efficiency allows higher output
compared to analog amps. |
|
3. Light weight : High efficiency means less heat
generation, allowing for reduction in heat sink size and weight. |
|
4. Size reduction : amp is smaller due to smaller
heat sink. |
