need for modulation

hi friends,

i need a Schematic diagrams for the following modulation types (i will donate 5 points for each diagram):

1. amplitude modulation (all its types)
2. frequency modulation
3. phase modulation
4. ASK modulation
5. PSK modulation
6. FSK modulation

i need them using the OP-AMP

Many thanks
 

amplitude modulation circuit diagram

the schematics for the AM transmitter and receiver is shown below.


I hope u what u wanted.

all d best

whats the need of modulation

this is to be simple to build in the laboratory for the students as well as the analysis and all the calculations will be simple and very clear
 

what is modulation with diagram

any help please?
 

balanced modulator circuit diagram

no 1 can help me?
 

transmitter modulation circuit diagram

Hi,

I managed to get these schematics of AM using op amps.check them out!


Hope you got what u were looking for.

amplitude modulation with diagram

Hi,


Here s the schematic for FM TX. given below is the circuit description.

Parts List:

R1 4K7 R4 150K R7 3K9 (2K7)

R2 4K7 R5 220R R8 120R (82R)

R3 4K7 R6 4K7

All resistors except R8 are at least 0.25W rated. R8 is at least 0.5W rated
(the 0.6W metal film M-series from Maplin can be used for R1-R8).

C1 1n C4 22uF C7 10n C10 1n

C2 4u7 C5 1n C8 1n

C3 1n C6 10n C9 33pF

VC1 5-60pF IC1 LM358 Q1 ZTX108


Regards

i do not know the second circuit, can you explain it please as it is not clear for me as a parts

Added after 3 minutes:

i donate for you 10 points for AM_transmitter_using_opamps.JPG

and 10 points for the FM_TX_using_opamps.gif

thanks
