List I (Logic family) | List II (Characteristic of logic family) | ||
---|---|---|---|
A. | TTL | 1. | Maximum power Consumption |
B. | ECL | 2. | Highest Packing Density |
C. | NMOS | 3. | Least Power Consumption |
D. | CMOS | 4. | Saturated Logic |
List I (VCR system) | List II (Azimuth angle) | ||
---|---|---|---|
A. | VHS | 1. | 7° |
B. | Video 2000 | 2. | 15° |
C. | Betamax | 3. | 6° |
List I | List II | ||
---|---|---|---|
A. | Copper | 1. | produces discrete energy level just above valence band |
B. | Rubber | 2. | produces discrete energy level just below conduction band |
C. | Antimony | 3. | large forbidden gap |
D. | Boron | 4. | valence and conduction bands overlap |
Therefore VSWR is infinite because |rv| = 1.
