www.analog.comcircuit, the amplifier biasing must also be noiseless, that is free from noise added directly or indirectly by the biasing (see Reference 1). Resistors with DC across them should have low excess noise (film types), or be AC-bypassed. Thus R1, R2, R3, R4, R7, and R8 are preferably metal films, with R7-R8 bypassed.

Generating Sequences With Recurrent Neural Networks
arxiv.orgA method for biasing the samples towards higher probability (and greater legibility) is described, along with a technique for ‘priming’ the sam-ples on real data and thereby mimicking a particular writer’s style. Finally, concluding remarks and directions for future work are given in Section 6.
