What is difference between RF and IF?
RF to IF conversion is achieved using a RF device called Down-converter. Heterodyne and homodyne receiver architectures are used to convert modulated RF signal to IF signal. Superheterodyne uses 10.7MHz as first IF and 470KHz as second IF….RF vs IF.

What is the difference between AF and RF amplifier?
AF amplifier is used for audio frequencies, i.e. from 20 Hz to 20 Khz. RF amplifier is used for radio frequencies, i.e. 500 KHz upwards.
What are the applications of signal generator?
RF and microwave signal generators. RF (radio frequency) and microwave signal generators are used for testing components, receivers and test systems in a wide variety of applications including cellular communications, WiFi, WiMAX, GPS, audio and video broadcasting, satellite communications, radar and electronic warfare …
Which amplifier is used for audio frequency?
Ultrasonic amplifiers are a type of audio amplifier handling frequencies from around 20 kHz to up to about 100 kHz ranges. These are usually designed for specific purposes such as ultrasonic cleaning purpose, metal fatigue detection technique, ultrasound scanning purpose, remote control systems, etc.
Do amplifiers increase current?
An amplifier (often loosely called an “amp”) is an electromagnetic or electronic component that boosts an electric current.
What was the first amplifier called?
triode vacuum tube
What is a high gain amplifier?
A “high gain” distortion amp is just that. Tweaked for heavy gain. JCM-900, Dual Rectifier, etc, etc. It will provide a highly distorted or overdriven tone at quiet to loud volume, any volume setting. They will often have a clean channel, though.
Is gain a distortion?
That first stage is the preamp stage. On some amps, you can control the level or strength of the signal sent through this first stage; this control is called “gain” (also often labeled as “drive”). Setting the gain control sets the level of distortion in your tone, regardless of how loud the final volume is set.
How does a high gain amplifier work?
Gain is basically a measure of how much an amplifier “amplifies” the input signal. For example, if we have an input signal of 1 volt and an output of 50 volts, then the gain of the amplifier would be “50”. In other words, the input signal has been increased by a factor of 50. This increase is called Gain.
