| + | ===== Noise Syntax ===== | ||
| + | |||
| + | //This section contains descriptions which are not implemented yet in simualtor. Work is in progress.// | ||
| + | |||
| + | Spice .noise command syntax is implemented: | ||
| + | |||
| + | ''.noise V(<N1>[,<N2>]) <VIN> <ac_description>'' | ||
| + | |||
| + | * <N1>, <N2> - output node numbers, if N2 is omited ground is implied; | ||
| + | * <VIN> - input AC source at which noise power will be calculated; | ||
| + | * <ac_description> - gnucap AC simulation statement. | ||
| + | |||
| + | Here are some examples: | ||
| + | |||
| + | * ''.noise V(6) Vin dec 10 20 20k'' | ||
| + | |||
| + | - noise at node 6 w.r.t. ground, calculated to **Vin**, noise power densinty will be calculated | ||
| + | using **10** points per **dec**ade (logarithmic scale) in frequency range from **20Hz** to **20KHz** | ||
| + | |||
| + | |||
| + | * ''.noise V(6,3) VSRC oct 2 10 10k'' | ||
| + | |||
| + | - noise between nodes 6 and 3, calculated to **VSRC**, noise power densinty will be calculated | ||
| + | using **2** points per **oct**ave (logarithmic scale) in frequency range from **10Hz** to **10kHz** | ||
