[0036] The number of moving terminals of the first single-pole multi-throw switch matches the number of moving terminals of the second single-pole multi-throw switch,
[0037] The amplification and attenuation device is used to realize switching of amplification and straight-through of the output signal of the second single-pole multi-throw switch.
