Scientific equipment and services and techno instruments are both iso 9001: 2000 certified company engaged in manufacturing of complete laboratory experiments measuring instruments for bs and ms laboratories of physics, electronics and electrical engineering.
The company manufactures electronics and physics experimental setups.
The modulation and demodulation set-up consists of modulating and demodulating circuits. It is provided with a fixed frequency [70khz] oscillator, which may be used for carrier frequency. This eliminates the need of a r.F. Oscillator. The carrier signal may be given from any other oscillator also, if the change in carrier frequency is desired. Since the circuit is designed for comparatively low frequency [70khz to 150khz] carrier signal, the usual oscilloscope is good enough.
