“Tengo un circuito CMOS con un paso de salida que genera una señal de buena potencia de 1 MHz. ¿Puedo utilizarlo como transmisor para la banda de ondas medias?”

Las señales rectangulares son ricos en armónicos y por lo tanto no se deben utilizar en un transmisor a menos que se tenga una buena etapa de filtración que separe sólo la señal de la frecuencia deseada en forma senoidal. Así, un transmisor con señal rectangular generaría una enorme interferencia en una buena parada del espectro, lo que no es deseable. Para transmisores, la señal del oscilador y luego amplificado si es necesario, debe ser lo más cercano como sea posible de la forma de onda senoidal. Los filtros utilizados en las salidas de los transmisores apuntan precisamente a eliminar los signos de las frecuencias indeseables que puedan irradiarse junto con el signo de la frecuencia fundamental.
