The FM modulator circuit (frequency modulation) is built with a Motorola MC1648P oscillator. Two varactors, Motorola MV-209 are used to frequency modulate the oscillator. The 5000 Ω potentiometer is ...

Below shown circuit diagram is the simplest pulse position modulation circuit using IC-555. With this type of circuit, the position of each pulse changes. Both width and period of the pulses vary with ...

The upshot of this operation for use as a pulse-width-modulator circuit is an approximate triangle wave (Fig. 2). The triangle wave is employed as the input to op-amp U2. U2 is a 741 op amp that's ...

Here we report a flexible all-graphene modulator circuit with the capability of encoding a carrier signal with quaternary digital information. By exploiting the ambipolarity and the nonlinearity ...

Its designer [acidbourbon] remarks that the circuit bears a striking resemblance to a ring modulator,so has taken it down that path by producing a 74HC based ring modulator guitar pedal.

This series features a built-in Delta-Sigma (ΔΣ) modulator, enabling the IC to ... used in magnetic sensors with the ASIC/analog circuit technology used in silicon semiconductors.

The LED is connected to a simple analog modulator circuit, which takes an audio signal as its input and sends the data to the light. The solar cell sends its data, with the help of a capacitor ...

A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled ... reconfigurability of the new variant can be exploited for analog circuit design,” states the ...
