At cutoff, the JFET channel is at its widest point completely closed by the depletion region extremely narrow O reverse biased

1- 2- 3- 4- 5- s, True or False, and correct the error if there is. The solid-state relay depends on the electric field to control the output moving parts. At the solar cells, the long wavelengths generate electron-hole pairs at near the surface. The IMPATT is a noisy system because it depends on the avalanche break down. The BARITT diode depends on thermionic emission rather than avalanche multiplication. For IMPATT and BARITT microwave devices, the frequency generation is inversely proportional to the drift region length. 6- The Gun diode depends on the avalanche break down.

2.→In communications theory, the signal-to-noise ratio (SNR) is defined as the ratio of the power of a signal (meaningful information) to the power of the background noise, that is,.. Psignal SNR = ··.·The SNR is usually measured in decibels. In the case of a cable modem, it is↓ P noise a measure of the signal strength to and from the modem relative to the background noise. The ideal SNR range is 30 to 50 decibels (dB). High noise or low signal power levels reduce the SNR and can negatively affect internet connectivity, resulting in data loss or slow speeds.↓ ↓ Home cable modems have a web interface at an internal LAN address such as 192.168.100.1 which gives the status of various modem parameters. For example, part of the status page of a modem at a given moment (a snapshot) is shown below.↓ a) For Channel 12 in the table, the SNR is given in decibels. What is actual signal to noise power ratio?↓ b) For the same channel, assume that the resistances R, and Ro are equal. Then the…
