The RF signal is however prevented by LC filters from flowing into the power supply. The amplifier works with either 50 ohm or 75 ohm antenna. It has a gain of 25 … 30 dB. MOSFETs are used to avoid ...

The circuit is designed for high analogue signal fidelity (as is, it would need the pulses to be generated with an DAC delivering a signal with appropriate upper and lower signal levels), but dipping ...

1. The block diagram shows how three low-power audio amplifiers (LM386) are configured to implement a triple-waveform generator at one of two selectable frequencies. The triangular signal goes to ...
