1,221,505. Transistor oscillators. TELEFONAKTIEBOLAGET L. M. ERICSSON. ] May, 1969 [2 May, 1968], No. 22339/69. Heading H3T. An oscillator, whose frequency can be varied without increasing the harmonic distortion, comprises: an amplifier T1, T2 having one input and two outputs, with a high input impedance, and low output impedances, the amplification at the first output being one, and the amplification at the first output being one, and the amplification at the second being greater than one; a resistor R2 and two series connected capacitors Cl, C2 connected between the input and earth; and a connection via a resistor R<SP>1</SP>, from the junction between the capacitors to the second output and via a variable resistor R<SP>11</SP>, to the first output. |
