impedance mismatch in a sentence

Examples

1. Common causes of echo include impedance mismatches in analog circuitry and acoustic coupling of the transmit and receive signal at the receiving end.
2. At frequencies below 10 MHz the impedance mismatch between a 50 ohm connector or cable and a 75 ohm one has negligible effects.
3. In DSL circuits, impedance mismatch often cause attenuation distortion so severe that some frequencies must be automatically mapped out and not used.
4. By measuring the magnitude of the impedance mismatch at the transmitter output it reveals problems due to either the antenna or the transmission line.
5. For example, in mixers mismatch loss occurs when there is an impedance mismatch between the RF port and IF port of the mixer.
6. The polyimide cap protects the screen and helps reduce any impedance mismatch that might occur when the wave crosses from the air into the device.
7. Would the relationship of the vacuum energy to the mass-energy of air give a sense of the impedance mismatch between air and vacuum?
8. This leads to problems when trying to translate programming objects to and from their associated database rows, a problem known as object-relational impedance mismatch.
9. RDBs were used for these roles in most cases, although saving objects to a RDB can be complicated, a problem known as object-relational impedance mismatch.
10. When the compression waves reach areas of high acoustic impedance mismatch ( such as the opposite side of the target ), tension waves reflect back and create spalling.
