Hello!
I have attached some image. In the first figure (pic1), you just see a simple FM transmitter. On the basis of this, I have some doubt.
A transmitter must contain a coil , transistor, variable capasistor,and an antina.
These itoms also depends on circuit volt.
1) What is the relation between frequency , wave’sgeographical spread area and uH?
(Frequency,wave) relation with “uH”
2) What is noise. How it depends on the circuit. How to suppress this?(look pic 2)
3) Relation between uH and coil’s(turn,radious,type(linear,circle..) diameter of coper wire)
uH coil relation and varience with power(in volt)
4) What is the relation between coil and transistor?
5) We use trim capasistor to tune. How its capacitance depends upon the coil,frequency and power?
6) If I need to build 1GHz frequency transmitter. Then what will be the value of uH,transistor,trim capasistor and power(in volt)? Also what type of antina is used?
7) (Frequency, power)-antina relation?
8) I saw some FM transmitter are connected with earth. What is the uses of earthing?
