| - | * Updates: | + | |
| - | * Implemented non-inverting amplifier with DC bias. Currently attempting to send just one pulse, so using a gain of about 110 V/V. {{ :wind_sensor:one_pulse_amplifier.jpg?direct&600 |}} | + | |
| - | * The disadvantage to having this amplifier is that the noise is also amplified which causes the voltage comparator to trigger falsely. | + | |
| - | * Attempting to use the Schmitt Trigger to "qualify" the signal before registering it as a valid response. This should solve the above problem. | + | |
