radio frequency amplifier उदाहरण वाक्य

उदाहरण वाक्य

1. The idea is to reduce the incoming frequency, which may be, say 1, 500, 000 cycles ( 200 meters ), to some suitable super-audible frequency that can be amplified efficiently, then passing this current through a radio frequency amplifier and finally rectifying and carrying on to one or two stages of audio frequency amplification.
2. The noise figure can also be seen as the decrease in signal to noise ratio ( SNR ) caused by passing a signal through a system if the original signal had a noise temperature of 290 K . This is a common way of expressing the noise contributed by a radio frequency amplifier regardless of the amplifier's gain.
