What is alignment in radio receiver?

Alignment is a process where several stages of the receiver are properly tuned to the desired frequency. The input to the audio stage is a demodulated message signal and does not require any alignment to receive the desired frequency.

What is RF alignment?

Re: What’s RF alignment? It is adjustment of each stage of a radio frequency device such that the desired bandwidth, center frequency, and amplification (or attenuation) is obtained from the device.

What is the purpose of correct alignment for intermediate frequency in an AM FM radio receiver?

The main reason for using an intermediate frequency is to improve frequency selectivity. In communication circuits, a very common task is to separate out, or extract, signals or components of a signal that are close together in frequency. This is called filtering.

What is sweep function generator?

A sweep generator is a piece of electronic test equipment similar to, and sometimes included on, a function generator which creates an electrical waveform with a linearly varying frequency and a constant amplitude. Sweep generators are commonly used to test the frequency response of electronic filter circuits.

How do you align a tube radio?

To align, use the same procedure as the AA5: 1) Align IF transformers to10. 7 MHz; 2) Align dial pointer to the dial scale; 3) Send a tone on an RF frequency into the set, tune the radio to that frequency, and adjust the antenna and oscillator trimmers to maximum AC voltage at the speaker voice coil.

What factors should be considered when selecting an intermediate frequency?

Abstract: The selection of an intermediate frequency for a super-heterodyne receiver involves consideration of the signal frequency, the tuning range, the pass-band width, the minimizing of spurious responses, regeneration stability, and frequency stability.

What are the requirements of sweep generator?

Sweep Generator:

• The sweep must be linear (the sweep voltage must rise linearly to the maximum value required for full screen horizontal deflection of the spot).
• The spot must move in one direction only, i.e. from left to right only, else the signal will be traced backwards during the return sweep.
