The transistor amplifier with characteristics of low input impedance and high output impedance is the common?

The common base transistor amplifier is characterized by low input impedance and high output impedance. This configuration is particularly useful in certain applications, such as in RF (radio frequency) amplifiers. The low input impedance means that it can work well with signal sources that have low output impedance, allowing the amplifier to effectively draw current from the source. At the same time, the high output impedance allows the amplifier to drive loads that may not require a significant amount of current, preserving the voltage across the load.

These characteristics make the common base configuration suitable for applications where high frequency response and voltage gain are required. In summary, the description of low input impedance combined with high output impedance aligns well with the functionality and applications of the common base amplifier.
